As I posted elsewhere, it's been estimated that every pronounceable set of letters in the English language will be registered as a domain name by 2017*

Sooner or later we're going to have to work out an approach to globally distributed names that's less naive than "somebody else chose that first, choose a different name!"

*Yes, I made that "fact" up myself.

The projects have very different goals so I don't think there will be too much confusion.
