More on the “if Tuvalu sinks, what will happen to .tv domains” thing. Paul wrote in with some domain expertise:
“… when the USSR collapsed they had the .su top level domain (TLD), all the separate republics Russia, Estonia, Moldovia, etc. got their own TLD and the .su domain was frozen and is now unused. Even though the www.tv people have the authority to sell the domain, that authority is given to them by the government of Tuvalu, if Tuvalu goes away, they no longer have the authority to sell a domain or have someone sell their TLD for them.”
Yikes. Update: Paul found that some .su domains are still up, and there’s a movement to try and save them. Maybe existing .tv addresses would remain, but new ones wouldn’t be registered if Tuvalu sank.
