2. The system of claim 1, further configured to support go-to operations for a user viewing at least one component of the multimedia document, including at least one of a group consisting of a frame-number based operation and a time-code based operation.

3. The system of claim 1, further configured to enable respective first and second users to:

access at least a third multimedia document at a remote storage subsystem, the remote storage subsystem being remote from the first physical premises and the first and second user devices and being in communication with a wide area network,

wherein the third multimedia document (a) has a universal format that defines the third multimedia document as a collection of components in multi media (b) has a structure that captures the relationship among the components and their spatial layout, and (c) also include hyperlinks; and

view, respectively using the first and second client devices, at least one component of media associated with the third multimedia document.

4. The system of claim 1, further configured to

cause multiple playbacks of at least one component of the media associated with the multimedia document accessed from the audio-video storage subsystem.

5. The system of claim 1, further comprising:

a third client device in communication with a wide area network,

the system further being configured to enable a user of the third client device to;

access the first multimedia document stored at the audio-video storage subsystem, and

playback at least one component of the media associated with the first multimedia document, using at least the operations of start, stop, and pause.

6. The system of claim 1, wherein the system is further configured to cause access to a multimedia resource, in communication with a wide area network, to cause viewing, at both the first and second client devices, of media from the multimedia resource.

7. The system of claim 1, further configured to cause:

buffering, at each of the first and second client devices, of a flow of data associated with the respective viewed component of the first multimedia document.

8. The system of claim 1, further configured for wireless communication with at least one of the first and second client devices.

9. The system of claim 1, further comprising at least one storage facility in communication with the wide area network, the storage facility configured to store at least one of pointers and hyperlinks to at least one component of a multimedia document.

10. The system of claim 1, further configured to enable at least the first and second users at the respective first and second client devices to communicate using at least one communication type selected from a group consisting of video conferencing, application sharing, computer-integrated telephony, and real-time text.

11. A content storage system comprising:

at least one audio-video storage subsystem at a first physical premises and configured for storing at least first and second multimedia documents, respectively created by first and second users using respective first and second client devices,

wherein both the first and second stored multimedia documents (a) have a universal format defining the multimedia document as a collection of components in multi media and (b) have a structure that captures the relationship among the components and their spatial layout and (c) also include hyperlinks; and

wherein the first and second client devices are separated by at least one wide area network and in communication with the audio-video storage subsystem, and have access to at least the first and second multimedia documents when stored on the audio-video storage subsystem,

the system being configured to

enable users of the first and second client devices each to add to at least both the first and second multimedia documents by using software tools respectively at the first and second client devices,

tag, with tag data, at least one portion of at least one of the first and second multimedia documents such that the tagged data can be searched later to access the tagged multimedia document; and

allow at least one user to search the tagged data to access the tagged multimedia document.

12. The system of claim 11, further configured to enable respective first and second users of the first and second client devices to cause playback of at least one of the respective components of the media associated with an accessed first and second multimedia document, and to operate on the playback using at least one of the group of operations consisting of start, stop, pause, fast forward, and reverse.

13. The system of claim 11, further configured to enable respective first and second users to:

view at least a third multimedia document at a remote storage subsystem that is in communication with a wide area network,

wherein the third multimedia document (a) has a universal format that defines the multimedia document as a collection of components in multi media and (b) has a structure that captures the relationship among the components including spatial layout, and (c) also includes hyperlinks;
