*when* we go to UTF8-over-EDNS (hehe) it will be important to make it
enticing to users and developers. Keeping as many rules as similar as
possible across the methods will be important to the latter camp. If they
have a web form which allows input, they won't want to have server-side
and client-side input controls based on whether the input is ASCII or
UTF8. That would be really hard.

Sticking with 63 "characters" means that input rules work the same whether
they are ASCII or UTF8.

Usability will be the defining factor for success, IMO. Making it hard to
deploy is self-defeating.
