You're right that customers can't recompile and many can't or won't reinstall
a new name server or anything else. Like I said, this kind of hashing stuff
either has to be completely user visible, or it has to be a fiction maintained
(and hidden) by the root servers.
I've received a request to move this discussion to some non-nanog list, which
isn't unreasonable. I've about said my piece anyway. Meet me on bigz if you
have more to say.
