I would love to watch this, but O'Reilly's presentation streamer is awful. I tried jumping ahead, but the video stream doesn't actually jump with me so I end up listening to one part and watching another (tried under FireFox, Safari and Chrome on Mac). I don't suppose someone has an alternative version somewhere?
