Here is a interesting method for sharing your broadcast, films and video content with live streaming technology. You can broadcast directly to your viewers. Each viewer in turn becomes a miniature broadcaster and amplifies your broadcast across the web.
BitTorrent Live is a powerful new web-based live streaming technology. Designed to eliminate barriers to broadcast, Live is an entirely new protocol, designed to deliver high quality video to large audiences - with significant reduction in infrastructure cost and network delays.
BitTorrent Live is currently in open beta. http://live.bittorrent.com/
