Saw this via slashdot - Fora.tv: "...delivers discourse, discussions and debates on the world's most interesting political, social and cultural issues, and enables viewers to join the conversation. It provides deep, unfiltered content, tools for self-expression and a place for the interactive community to gather online."
The video quality is quite good...but, in reality, not everyone is suited to be a presenter in the online video medium - especially when we are looking at 40+ minute lectures. Boredom sets in quickly. Perhaps I'd be more inclined to watch on a video iPod while travelling.
