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 BitTorrent Live with the idea of killing TV. I agree that "people love what they see on television, but want it accessible from the Web", but one of the main reasons why is that people don't want to watch TV live (other than sports, which has even more geographical licensing problems than regular TV).
