AC#1, you said 'It'll be a California based "NGO" controlled by the US Government by means of California "law" and US federal "law" including "secret" "courts" and "secret" letters and suchlike.'
If you actually read the names community proposal, it would be a California Public Benefit Corporation controlled by ICANN itself, after the end of ICANN's government contract. But this proposal isn't agreed by any means yet. As for the FISA court and National Security Letters, yep, they're kind of hard to get away from, although since IANA publishes contact data for all registrations, I don't quite know what would be subject to a FISA warrant or an NSL.
In case you wonder, I greatly dislike the fact that IANA lives under US jurisdiction, but that's life.
