BitTorrent Live is a powerful new live web streaming technology. Designed to eliminate barriers to broadcast, Live leverages parts of the BitTorrent protocol to deliver high quality video to large audiences - with significant reductions of infrastructure costs and network delays.

BitTorrent Live is currently under development in Beta. Do you regularly webcast? Do you want to help us invent the future of live streaming? See if you qualify to participate in our Beta program.

I have seen people use this in the past and the issue is with Peer-to-peer if you have many people watching with very low bandwith or on mobile divices the quality of the video will go way down. I wouldnt use it for a main CDN but it would be cool to use as a secondary one.

Is this worth using?
