Streamer P2P Radio
I'm not sure what the theoretical limit for total connected users might be, but the idea of Internet radio peers sharing bandwidth to distribute a stream is certainly well within the concept of smart radio broadcasting. Streamer isn't currently offering any content I consider must listen radio. On the other hand, the technology is perfect for distributing your own radio broadcast to the masses. Current stations seem to be pirate outfits broadcasting commercial music and copyrighted content in definance of distribution rules. Don't let this stop you from creating something more unique featuring music from artists who don't have major label backing. The software uses each additional listener's Internet connection to balance the bandwidth used, allowing the number of potential listeners to grow as the number of actual listeners grows. The pirate component works by disguising the stream's point of origination. For more detailed info on what makes Streamer tick, read the How it Works section of the site.
