I'm (positively) surprised. I don't condone what he's doing, but refusing to speak to him will not make the attack not happen. He would simply do it anyway. We can still do whatever we can to stop him from succeeding. Having a direct line of communication to your enemy is mutually beneficial.

Can someone record a screencast of the attack and post it to youtube? It would be interesting to watch the video afterwards in case there are some lessons that could be learned. There was a guy who recorded the Mt. Gox first incident when the prices fell to below one usd. It was interesting to watch his reaction and comments. That time it was only a fluke that he could get in on tape. This time we could be prepared and have analyzing software running and ready for the 19001 block (when the attack is scheduled).
