Taste3 has posted videos from some of last year's speakers. I've linked directly to Dan Barber's opening talk above, which was one of my favorites from the conference. I'll be heading back to Napa in May this year to speak again at Taste3 "on the power of online technology and social networking as it intersects the food and wine world." I'm really happy to see they've posted these talks. Not enough conferences share their talks after the fact.
