Having to deal with what codepoint is allowed or not is still okay for
us (albeit easy since Unicode has done nice classification on
codepoint). This can be QED in nameprep.
Hence I am more inclined for the first option, ie. ask the Unicode
people to help us on this. (Okay, before you going to hit me with that
stick, I know there are other issues with this proposal...but I shall
leave it to Patrik to solve been the liason between IETF & UC :-)

I would like to see that happened but not without Unicode people input.

Yet another definiation of "hostname" *doh* :-) I believe there is one
already in the Requirement I-D.

Ah, I heard something about "one useful product of IDN WG is having a
defined doc on how to use Unicode characters in Internet protocol"...I
am not sure if that is a good or bad sign...
