	Uh, no.  Re-read that message again.  I'm talking about 
clustering of names around certain common sequences of characters. 
Unless you want to hand out the ccTLDs in a totally random fashion, 
they will start running into collision problems much sooner than 
that.  Most hashing algorithms start having problems when they get 
close to 50% full.  There's no difference here.
