If you want to distribute video as well as music, then Popcast is a method for easily broadcasting on your own TV channel. The Popcast system technically parallels BitTorrent and RSS (really simple syndication) implementations but the technical comparison ends there. The Popcast system extends the technical platform with a Popcast-specific Macromedia Flash API, private tracker network and custom publishing tools to simplify channel production and channel viewing. You'll find the player on the February 2006 Edition's Cover Disc.
Popcast has 260 Channels, 522 Shows, with 14574 Subscribers. Though not a lot are worth watching just yet (Click here to view a screenshot).
