9. A method as recited in claim 1, wherein the determination whether the mobile data message requires communication policy compliance handling includes:

accessing a location register to obtain subscriber profile data associated with a sender of the mobile data message or the intended recipient of the mobile data message; and

determining based on the subscriber profile data obtained from the location register, whether the mobile data message requires communication policy compliance handling.

10. A method as recited in claim 1, further comprising performing communications policy compliance processing on the mobile data message.

11. A method as recited in claim 1, wherein the determination whether the mobile data message violates the communication policy is made based at least in part on metadata extracted from the mobile data message.

12. A method as recited in claim 1, wherein the determination whether the mobile data message requires communication policy compliance handling includes analyzing the contents of the mobile data message to determine whether communication policy compliance handling is required based on the analysis of the contents of the mobile data message.

13. A method as recited in claim 1, further comprising determining whether the mobile data message is required to be modified to comply with a communication policy and modifying the mobile data message prior to its being delivered to an intended recipient associated with the mobile data message if it is determined that the mobile data message is required to be modified to comply with the communication policy.

14. A method as recited in claim 1, further comprising determining whether a communication policy requires that archive data associated with the mobile data message be stored and storing said archive data if it is determined that the communication policy requires said archive data to be stored.

15. A method as recited in claim 14, wherein said archive data comprises metadata extracted from the mobile data message.

16. A method as recited in claim 14, wherein said archive data comprises at least a portion of the contents of the mobile data message.

17. A method as recited in claim 1, further comprising forwarding the mobile data message to an intended recipient associated with the mobile data message.

18. A method as recited in claim 17, wherein forwarding the mobile data message comprises determining whether a source identifier associated with the mobile data address should be changed.

19. A method as recited in claim 17, wherein forwarding the mobile data message comprises determining whether a source address associated with the mobile data address should be changed.

20. A method as recited in claim 17, wherein forwarding the mobile data message comprises determining whether a reply path associated with the mobile data address should be changed.

21. A method as recited in claim 17, wherein forwarding the mobile data message comprises determining whether data associated with the mobile data address should be changed as required to ensure that a reply mobile data message sent by the intended recipient in reply to the original mobile data message is routed to the communication policy compliance destination.

26. A method as recited in claim 1, wherein sending the mobile data message includes opportunistically sending the mobile data message.

27. A method as recited in claim 26, wherein the mobile data message includes a secondary data message and the mobile data message is sent opportunistically using channel bandwidth that is not being used to exchange data of a primary type.

28. A method as recited in claim 9, wherein the location register includes at least one of a home location register or a visitor location register.

22. A method of processing redirected mobile data messages, comprising:

receiving at a communication policy compliance destination a redirected mobile data message that is transmitted at least in part via a mobile communication network, is received from a sending mobile device, and includes at least some message content generated at the sending mobile device; and

performing at the communication policy compliance destination communication policy compliance handling on the redirected mobile data message using a processor, including;

determining whether the mobile data message violates a communication policy associated with the mobile data message; and

blocking the mobile data message from being delivered to the intended recipient associated with the mobile data message if it is determined that the mobile data message violates the communication policy.

23. A method as recited in claim 22, further comprising forwarding the mobile data message to the intended recipient if it is determined that the mobile data message does not violate the communication policy and is not otherwise required to be blocked.
