I have this problem, except I preemptively struck. I grabbed sunir.org before someone else did. Now there is a company, Sunir Networks, with my name. Moreover, the pricks that run Network Solutions (now Verisign) have graciously squatted on sunir.com. Also, Sun Microsystems has a division named SunIR (Sun Information Resources).
So, do I really have more right to sunir.org than anyone else? I certainly think so. Can I defend myself if challenged by someone as evil as Sun? Doubt it.
Since I now really heavily on my domain being consistent, if I get challenged, I'll be totally screwed. It's like my calling card now. But I'm lucky in that my name is relatively rare in the world. I can't imagine what would happen if my name was John Smith. And no, before you ask, I don't have any middle names.
Really, as we all know, the problem with the DNS service is that it is a relatively flat namespace. Actually, it's completely flat if you're trying to make money. Either you're a .com or you're toast. Even my friends and family can't get it right. My father actually said, "Dot what?" Like how hard is it for someone who played a hand in naming me to remember sunir AT sunir DOT O-R-G. Apparently impossible.
As the world gets more and more connected, the whole notion of identity is going to get squeezed until it pops. "It's a small world after all, and there ain't enough room for both of us. Get off."
Global village, indeed. Stuff yourself.
"Look! You're free! Go, and be free!" and everyone hated it for that. --r
