cc:s trimmed.  I'm not on the w3c list anyway, and I don't think the
IESG cares about this detail.

Before those who think DNS weenies never listen to real-world problems
jump in, I want to point out what _I_ understand to be a problem.  If
you're a DNS geek, then the natural thing to think is, "This is easy.
You just send a well-crafted UDP packet.  How hard could that be?
Once the typecode is assigned, what's the problem with sending an
unknown RR?"

If you're most application programmers, however, the entire conversation
ended at "send a well-crafted UDP packet".  Your libraries don't
support injecting well-crafted UDP packets, and you have no idea how
to do that, and it's incredibly stupid, and why would anyone think
that was reasonable anyway?

If you're most sysadmins, the entire conversation ended at "My tools
don't know what TYPE1234 is."  

If we seriously think that DNS RRTYPEs ought to be useful extensions
to people, we're going to have to make them _easy_ to deploy, not just
possible.  I have no idea how to solve this problem, though.

Best,

A
