i dont have any technical evidence to back this up but i feel like .ru domains tend to be pretty resilient to US take downs. i've seen so many blatantly illegal websites and/or hacking scripts hosted on .ru domains that seem to never go away. granted, i'm sure they also trigger spam filters like crazy.

.nz i could see catching on. there's got to be a much more 'friendly' TLD though. nz doesn't feel as generic as com/biz/net/org

who controls .mobi?
