More details have surfaced about Microsoft's upcoming Zune MP3 player, which is designed to rival the iPod. Apparently the plan is for Zune to use its wireless capabilities to be a social networking device, and not just a music and video player. According to documents filed with the FCC, Zune users will be able to play the role of a deejay, sending streaming music content to up to four other devices. With the device's wireless networking abilities turned on, people can send and receive photos, as well as "promotional copies of songs, albums and playlists," according to CNet News. Users also can choose whether to stream to any nearby Zune user or only to people on their friends list. With the deejay setting on, the music sent is the same as what the deejay is listening to. If they stop listening, the stream is interrupted. Toshiba will be manufacturing the Zune device.

Microsoft also has said that Zune will come preloaded with videos from the EMI label, but has not discussed the details of any music or video service it plans to offer. Microsoft does plan to have one model available in time for the holiday season, and the company expects the Zune effort to take years and cost hundreds of millions of dollars, according to CNet. Other features of the device will be a 30GB hard drive, a three-inch screen and an FM tuner. More details will be announced in the coming weeks.
