Since John buried this very important point a few
paragraphs into his message, I'd like to bring it
forward and reinforce it a bit.

I believe many of those who have proposed registration-based
restrictions have assumed that a restriction on, say, registrations in
.ie. to use only characters which are valid in Irish would somehow
apply to the characters allowed in hostnames under .example.ie.  As
John's point makes clear, this isn't true.  Ensuring that folks
outside this group understand this point may be critical to getting
reasonable deployment once IDN is in the wild.
