in response to the request, referencing a prioritized list of proximate client devices of the plurality of client devices being maintained on the server computer system, wherein the proximate client devices of the prioritized list are closest in proximity to the first client device, wherein at least one of the proximate client devices maintains a current version of the requested file;

choosing a second client device of the proximate client devices of the prioritized list, wherein the second client device is the closest in proximity to the first client device compared to other proximate client devices listed in the prioritized list and maintains the current version of the requested file;

communicating a location of the second client device to the first client device to allow the first client device to directly obtain the current version of the requested file from the second client device; and

transferring, from the second client device, the current version of requested file to the first client device.

2. The method of claim 1, wherein transferring is performed as a peer-to-peer file transfer over a Local Area Network (LAN) without having to access a Wide Area Network (WAN), wherein the network includes LAN, WAN, or the Internet.

3. The method of claim 1, wherein the prioritized list takes into account factors including one or more of physicality of the first and second client devices, the network, overall bandwidth of the network, available bandwidth of the network, time expiration of the requested file, file size of the requested file, time to transfer the requested file, and the current version of the request file.

4. The method of claim 1, wherein the peer-to-peer transfer of the request file comprises a peer-to-peer file sharing.

5. The method of claim 1, wherein the closest in proximity of the second client device to the first client device is based on a shortest transfer time required to transfer the request file or the location of the second client device being physically closest to the first client device.

6. The method of claim 1, further comprising updating the requested file from the current version to a newer version residing at a third client device of the proximate devices, wherein the newer version being newer than the current version of the second client device, and redirecting the first client device to directly obtain the newer version of the requested file from the third client device, and transferring the newer version of the requested file from the third client device to the first client device.

7. The method of claim 1, further comprising directing the first client device to a data source to obtain the requested file based on a predetermined time period having an expiration timeout that is tailored according to contents of the requested file, wherein the first client device is directed to the data source after the predetermined time period has reached.

8. An apparatus comprising:

a plurality of client devices coupled to a server computer system over a network; and

the server computer system to

receive a request, from a first client device of the plurality of client devices, a request for a file,

in response to the request, reference a prioritized list of proximate client devices of the plurality of client devices being maintained on the server computer system, wherein the proximate, wherein the proximate client devices of the prioritized list are closest in proximity to the first client device, wherein at least one of the proximate client devices a current version of the requested file,

choose a second client device of the proximate client devices of the prioritized list, wherein the second client device is the closest in proximity to the first client device compared to other proximate client devices listed in the prioritized list and maintains the current version of the requested file,

communicate a location of the second client device to the first client device to allow the first client device to directly obtain the current version of the requested file from the second client device, and

transfer, from the second client device, the current version of the requested file to the first client device.

9. The apparatus of claim 8, wherein transferring is performed as a peer-to-peer file transfer over a Local Area Network (LAN) without having to access a Wide Area Network (WAN), wherein the network includes LAN, WAN, or the Internet.

10. The apparatus of claim 9, further comprising a client connection detector having an input and an output, the input coupled to receive a signal when the first client device is connected to the LAN, and the second client device coupled to receive the client connection detector output indicating when the request file is transferred from the second client device to the first client device.

11. The apparatus of claim 8, wherein the peer-to-peer transfer of the request file comprises a peer-to-peer file sharing.

12. The apparatus of claim 8, wherein the closest in proximity of the second client device to the first client device is based on a shortest transfer time required to transfer the request file or the location of the second client device being physically closest to the first client device.

13. The apparatus of claim 8, further comprising a retrieval engine having a bi-directional communications port, the bi-directional communications port coupled to the directory server, the bi-directional communications port to receive the location from the directory server, receive the requested file from the second client device, and facilitate the first client device to receive the requested file from the second client device via the retrieval engine.

14. The apparatus of claim 8, wherein the server computer system is further to update the requested file from the current version to a newer version residing at a third client device of the proximate devices, wherein the newer version being newer than the current version of the second client device, and redirecting the first client device to directly obtain the newer version of the requested file from the third client device, and transferring the newer version of the requested file from the third client device to the first client device.

15. The apparatus of claim 8, wherein the server computer system is further to direct the first client device to a data source to obtain the requested file based on a predetermined time period having an expiration timeout that is tailored according to contents of the requested file, wherein the first client device is directed to the data source after the predetermined time period has reached.

16. A non-transitory machine-readable storage medium comprising instructions that, when executed by a machine, cause the machine to:

receive, from a first client device of a plurality of client devices, a request for the file transfer at a server computer system;

in response to the request, reference a prioritized list of proximate client devices of the plurality of client devices being maintained on the server computer system, wherein the proximate, wherein the proximate client devices of the prioritized list are closest in proximity to the first client device, wherein at least one of the proximate client devices maintains a current version of the requested file;

choose a second client device of the proximate client devices of the prioritized list, wherein the second client device is the closest in proximity to the first client device compared to other proximate client devices listed in the prioritized list and maintains the current version of the requested file;

communicate a location of the second client device to the first client device to allow the first client device to directly obtain the current version of the requested file from the second client device; and
