What's the worst they can do at this point? Make .bobtodd and .bubbagump TLDs? This is different from some of the crap we've got now in what way?? Well, ICANN has come pretty close to delegating .HOME and .CORP to domain speculators, despite the vast amount of informal use which would get badly

How long, exactly, do you expect 3.2 billion unicast addresses to provide enough addressing for 6.8+ billion people? Oh, I'd say a decade. Like I said, I have IPv6 on my server and my home broadband, which mostly works, with the emphasis on the mostly. We've just barely started to move from
