Iirr sky had a torrent client in it's pc 'app' for a while. I wonder how much more effective having a signed torrent file spread around your subscribers is compared to a really good cdn? Does anyone have any figures?

(by signed torrents I mean netflix gpg signs each chunk and so you can be assured the quality is top notch they can be fairly sure you get charged etc etc)

P2P is much slower than CDNs; e.g. Joost only got 1/3 of each stream from P2P (hardly seems worth the engineering effort).
