I think this article is remiss in not mentioning the dozen or so P2P live streaming systems that have been in production for years. Without any details (really, any at all), it's hard to connect this live BitTorrent with the idea of killing TV.
I notice that you aren't mentioning any either. Cohen is quoted as saying that current P2P protocols aren't good at handling large events.
I don't really follow this field so I can't name any players other than Adobe and Octoshape, but I know they are out there. My point is that Bram is pitching it like he invented P2P streaming — which he certainly didn't — and GigaOM and TechCrunch are eating it up because it fits some narrative that they know generates pageviews.
