3. The method of claim 2, further comprising:

receiving a second playback command during playback of the multimedia program; and

controlling the playback of the multimedia program responsive to the second playback command.

4. The method of claim 2, wherein receiving the playback command comprises receiving the playback command via an IMS and/or SMS messaging service.

5. The method of claim 2, further comprising:

receiving a voice signal during playback of the multimedia program; and

playing the voice signal concurrently with playback of the multimedia program.

6. The method of claim 5, wherein the voice signal is received via a protocol comprising MMS and/or VoIP.

7. The method of claim 2, further comprising:

receiving a voice signal during playback of the multimedia program;

interrupting the playback of the multimedia program responsive to receiving the voice signal; and

playing the voice signal while the playback of the multimedia program is interrupted.

8. The method of claim 2, further comprising:

transmitting a playback command from one of the plurality of subscriber mobile terminals to other of the subscriber mobile terminals during playback of the multimedia program by the other subscriber mobile terminals.

9. The method of claim 2, further comprising:

transmitting a playback command request from one of the subscriber mobile terminals to a control terminal; and

transmitting a playback command from the control terminal to selected ones of the plurality of subscriber mobile terminals responsive to the playback command request.

10. The method of claim 1, wherein the playback command is encrypted.

11. The method of claim 2, further comprising:

transmitting configuration data to one of the subscriber wireless terminals, the configuration data including control permissions for the one of the subscriber wireless terminals.

12. The method of claim 11, wherein the control permissions specify the permissions of the one of the subscriber wireless terminals to control playback of the multimedia program by the one of the plurality of subscriber wireless terminals.

13. The method of claim 1, wherein providing the multimedia program to the plurality of subscriber mobile terminals comprises transmitting the multimedia program over a first network, and providing the command to the plurality of subscriber mobile terminals comprises transmitting the command over a second network, different from the first network.

14. The method of claim 13, wherein the first network comprises the internet and the second network comprises a cellular communication network.

15. The method of claim 1, further comprising:

transmitting the multimedia program to a plurality of subscriber mobile terminals;

receiving the multimedia program at one of the plurality of subscriber mobile terminals; and

transmitting a notification from the one of the plurality of subscriber mobile terminals in response to receiving the multimedia program.

16. The method of claim 15, wherein transmitting the multimedia program to the plurality of subscriber mobile terminals comprises transmitting a confirmation address together with the multimedia program, and wherein transmitting a notification from the one of the subscriber mobile terminals in response to receiving the multimedia program comprises transmitting the notification addressed to the confirmation address.

17. The method of claim 1, wherein the multimedia program comprises an encrypted data file, and wherein transmitting the command to the plurality of subscriber mobile terminals comprises transmitting a file decryption key configured to decrypt the encrypted data file to the plurality of subscriber mobile terminals.

18. The method of claim 17, further comprising:

receiving the command including the file decryption key at the one of the subscriber mobile terminals;

decrypting the encrypted data file; and

initiating playback of the multimedia program.

19. The method of claim 1, wherein providing the multimedia program to the plurality of subscriber mobile terminals comprises transmitting the multimedia program using a first transmission protocol;

and

wherein transmitting the command to the plurality of subscriber mobile terminals comprises transmitting the command using a second transmission protocol, different from the first transmission protocol.

20. The method of claim 19, wherein the first transmission protocol comprises HTTP, FTP, SIP, and/or MMS, and wherein the second transmission protocol comprises SMS and/or SMTP.

21. A communication system comprising:

a plurality of subscriber mobile terminals configured to play a multimedia program; and

an originating terminal configured to provide the multimedia program to the plurality of subscriber mobile terminals and to provide a playback command to the plurality of subscriber mobile terminals, after providing the multimedia program, to control the playback of the provided program by the plurality of subscriber mobile terminals, thereby coordinating playback of the multimedia program by the plurality of subscriber mobile terminals.

22. The communication system of claim 21, wherein at least one of the plurality of subscriber mobile terminals is configured to receive the multimedia program, to receive the playback command from the originating terminal, and to control playback of the multimedia program responsive to the playback command received from the originating terminal.
