See Ya .su
Sarkastro writes "Wired has this story on the pending death of the .su domain. Since the Soviet Union broke up a decade ago, all of the former members now have their own ccTLDs. Now, some people are ready to see .su be put to rest, including ICANN who is quite firm in their stance. Others within the former Soviet Union would like to see it stick around as a geopgraphical area domain. Currently, .su domains cost $15,000 (.ru cost less than $30), so there are only about 28,000 registered. It's especially interesting to watch how the Internet reacts to geographical boundaries that no longer exist. It's easy to add a ccTLD, but much much harder to remove one."
Many countries are going to change their names in the future. The article doesn't really go into it, but I'm sure the name has some political overtones for many people in Russia. Some other names with political ramifications are .tw (taiwan) .cs (Czechoslovakia) .kp
and .kr (Koreas) etc.
There is also Hong Kong and Yugoslavia which still have top level domains. There is also the issue of what to do about occupied countries, especially where the occupier claims them as part of their own, e.g. Chechnia, Tibet, Hawaii and Palestine.
