While some don't mind setting up shop in the .us domain, others wonder why they can't set up their own top-level domains. Like .sex, for instance. The only reason InterNIC holds power over DNS is that all the local name servers in the world are configured to query InterNIC's servers. There's no reason a name server can't query your root name server as well as InterNIC's servers. If enough name servers around the world know to look through your servers when they get a domain name ending in .sex, it would work fine.
Truth is, there's nothing in DNS that precludes a little .sex.
