Is this correct: "under the Patriot Act, GoDaddy and Verisign would not be allowed to admit involvement if they were requested so by the agencies in charge of the supposed domain seizure"?
The PATRIOT act allows pretty much anything. In the case of a .com domain, there are only two parties that could possibly modify it (the registry or the registrar) so such a gag order is fairly pointless. People talking about ICANN modifying .com domains just don't understand how DNS works. (Although there's not much difference between ICANN and VeriSign — they're both The Man.)
