4. The method of claim 3, wherein selecting the leader device includes transmitting a link from the media output device to the leader device to trigger the leader device to access the converted media content stream from the media output device and to transmit the converted media content stream from the leader device to each of the media output devices of the group.

5. The method of claim 3, wherein selecting the leader device includes transmitting a link from the leader device to at least one other media output device of the group to trigger the at least one other media output device to access the converted media content stream from a location specified by the link.

6. The method of claim 1, wherein initiating transmission of the converted media content stream includes transmitting a link to each of the other media output devices to trigger the other media output devices to access the converted stream from the media output device.

7. The method of claim 6, wherein one of the other media output devices is selected as the leader device.

8. The method of claim 2, wherein the leader device is selected to be the same as the media output device, and wherein initiating transmission of the media content stream includes transmitting, as the leader device, the converted media content stream from the media output device to each of the media output devices of the group.

9. The method of claim 8, wherein as the leader device, the media output device controls timing parameters for synchronized playback of the media content from the group of media output devices.

10. The method of claim 8, wherein as the leader device, the media output device performs operations for at least one of playback control by the group of media output devices, or implementation of buffer control logic to monitor an amount of buffer data on each media output device of the group.

12. The method of claim 2, wherein implementing the output configuration includes selecting one of the media output devices of the group as the leader device based on a capability of the selected media output device.

13. The method of claim 12, wherein the capability corresponds to the selected media output device having a digital signal processor (DSP).

14. The method of claim 2, wherein implementing the output configuration includes selecting one of the media output devices as the leader device based on an amount of bandwidth that is available to the selected media output device as compared to other media output devices of the group.

15. The method of claim 2, wherein implementing the output configuration includes selecting one of the media output devices as the leader based on a user preference.

16. The method of claim 1, wherein implementing the output configuration includes detecting another media output device of the group as having previously been selected as the leader device, and then causing a switch with the detected media output device that was previously selected as the leader device, so that the media output device becomes the leader device.

17. The method of claim 1, wherein the point-to-point communication medium is implemented using a Bluetooth protocol, and wherein the second communication medium is implemented using an 802.11 protocol.
