Don't forget that 99% of names on the Internet are allocated by local 
administrators, NOT by the registries - because they are not second level 
domain names, but allocated UNDER those domain names.

At that point, it may be VERY wise to encourage implementations to "police" 
the registrations (with suitable possibilities for overrides, like BIND has 
today), since that's the only "policing" that exists.

I agree with you in principle - the transport protocol MUST remain able to 
transport (nearly?) everything, and the matter of which characters to 
choose to transport is an usage matter, not a DNS protocol matter.

But this group needs to consider that matter too. Carefully.
