similar
the idea seems similar, though more akin to a dynamically routed CDN where content as discrete chunks is distributed (wrapped in whatever protection the publishers want) and retrieved seamlessly ... bittorrent does this but at a much lower level on chunks within a file and isn't seamless to the other apps - media players etc.
LiveStation is an example of this being used for broadcast - http://blog.offbeatmammal.com/post/2008/09/15/Is-Peer-to-Peer-the-platform-for-next-generation.aspx
Ironically while this may help the telcos squeeze more out of the wire it probably won't reduce our bills... unless there is a way to account for the fact we're uploading "local" copies to our CCN neighbours and they're downloading from us and not incurring backhaul or interconnect fees we'll probably still get charged by the byte...
