Abstract

A user uses a lurker to check a colleague'"'"'s location electronically. If the colleague is at the location and a device is available for communicating with the colleague, a communications channel is established between a device near the lurker and the colleague'"'"'s device, and communication can begin.

Claims

1. A network lurking agent stored on a tangible computer-readable media, the network lurking agent comprising:

an inquirer designed to place an inquiry in a JavaSpace persistent store to determine the availability of an user in an environment, the JavaSpace persistent store including at least one of an environment setting to indicate the availability of the user in the environment, and a user preference setting to indicate whether a device in the environment is enabled to be used; and

a lurker designed to retrieve from the JavaSpace persistent store a response to the inquiry to indicate the availability of the user in the environment; and

a sender designed to send a message to the JavaSpace persistent store when the user is not available in the environment.

2. A network lurking agent according to claim 1, the network lurking agent further comprising a receiver designed to receive a message from the JavaSpace persistent store.

3. A system stored on a tangible computer-readable media to support network lurking, the system comprising:

a JavaSpace persistent store;

an environment setting stored in the JavaSpace persistent store, the environment setting including at least one of the availability of a device and a user in an environment;

a user preference setting stored in the JavaSpace persistent store to indicate whether a device in the environment is enabled to be used;

a network lurking agent designed to place an inquiry in the JavaSpace persistent store to inquire about the availability of the user in the environment; and

a network receiving agent designed to determine the availability of the user in the environment responsive to the inquiry from; and

the network lurking agent designed to send a message to the JavaSpace persistent store when the user is not available in the environment.

4. A system according to claim 3, wherein the system notifies the network receiving agent about the inquiry when the network lurking agent places the inquiry in the JavaSpace persistent store.

5. A system according to claim 3, wherein the network receiving agent and the network lurking agent are designed to open devices as a result of the inquiry, the devices enabling communication.

6. A system according to claim 3, wherein;

the network lurking agent is designed to place a message in the JavaSpace persistent store if the inquiry is refused; and

the network receiver is designed to refuse the inquiry and to receive the message from the JavaSpace persistent store.

7. A method for using a network lurking agent to electronically lurk to an environment in a system, the method comprising:

identifying an environment of interest; and

placing an inquiry as to the availability of a user in the environment of interest in a JavaSpace persistent store, the JavaSpace persistent store including at least one of an environment setting to indicate the availability of the user in the environment, and a user preference setting to indicate whether a device in the environment is enabled to be used; and

sending a message to the JavaSpace persistent store when the user is not available in the environment.

8. A method according to claim 7, the method further comprising responding to the inquiry by a network receiving agent.

9. A method according to claim 8, wherein responding to the inquiry includes accessing devices by the network lurking agent and the network receiving agent to enable communication.

10. A method according to claim 8, wherein responding to the inquiry includes:

refusing the inquiry by the network receiving agent;

placing a message in the JavaSpace persistent store by the network lurking agent;

retrieving the message from the JavaSpace persistent store by the network receiving agent; and

storing the message for later access from the environment.

11. A method according to claim 8, wherein responding to the inquiry includes:

placing a message in the JavaSpace persistent store by the network receiving agent;

retrieving the message from the JavaSpace persistent store by the network lurking agent; and

receiving the message at the network lurking agent.

12. A method according to claim 8, wherein responding to the inquiry includes determining the availability of a user in the environment according to an environment setting in the JavaSpace persistent store.

13. A tangible computer-readable medium containing a program to use a network lurking agent to electronically lurk to a location on a computer system, the program being executable on the computer system to implement the method of claim 7.

14. An apparatus stored on a tangible computer-readable media for using a network lurking agent to electronically lurk to an environment in a system, the apparatus comprising:

means for identifying an environment of interest; and

means for placing an inquiry as to the availability of a user in the environment of interest in a JavaSpace persistent store, the JavaSpace persistent store including at least one of an environment setting to indicate the availability of the user in the environment, and a user preference setting to indicate whether a device in the environment is enabled to be used; and

means for sending a message to the JavaSpace persistent store when the user is not available in the environment.

15. An apparatus according to claim 14, the apparatus further comprising means for responding to the inquiry by a network receiving agent.

16. An apparatus according to claim 15, wherein the means for responding includes means for accessing devices by the network lurking agent and the network receiving agent to enable communication.

17. An apparatus according to claim 15, wherein the means for responding includes:

means for refusing the inquiry by the network receiving agent;

means for placing a message in the JavaSpace persistent store by the network lurking agent;

means for retrieving the message from the JavaSpace persistent store by the network receiving agent; and

means for storing the message for later access from the environment.

18. An apparatus according to claim 15, wherein the means for responding includes:

means for placing a message in the JavaSpace persistent store by the network receiving agent;

means for retrieving the message from the JavaSpace persistent store by the network lurking agent; and

means for receiving the message at the network lurking agent.

19. An apparatus according to claim 15, wherein the means for responding includes means for determining the availability of a user in the environment according to an environment setting in the JavaSpace persistent store.
