Architecture for content awareness and control among peer-to-peer communication devices

[0025]Referring first to FIG. 1, it is a block diagram depicting an exemplary environment 100 in which several embodiments of the present invention may be realized. As shown, each of a first communication device 102, a second communication device 104, and a third communication device 106 (also referred to as a host device 106) are in communication with other ones of the communication devices 102, 104, 106. And in this environment 100, only one of the communication devices 102, 104, 106—communication device 106—is in communication with a content presentation device 108.

[0026]In general, the depicted environment 100 is a social environment in which each person, in a group of people, operates one of the communication devices 102, 104, 106. And embodiments of the present invention enable the group of people to collaboratively select, for presentation at the content presentation device 108, a playlist (also referred to herein as a play queue) of content files that are distributed among all
