This is actually quite disturbing, as it seems to ignore due process in every way, shape, and form. (Side rant: I really wish I could figure out how to get the US Government down to about 1/20th its current size.)

It is also seems obvious to me that there will be a solution to this very soon: Underground DNS. Since only the DNS addresses were taken and it was facilitated by ICANN, I can't imagine that somebody else (I could even picture it being the Pirate Bay, once upon a time) saying "I'll play root for the sites that can't trust ICANN anymore."
