 Wow, is that a hack.  Wildcards don't do what we want, so we'll use
 zone cuts as faux wildcards.

I thiought this was a hack when I heard it during the meeting. But
I think that is could actually work.

Remember that the DNS is a lookup system, not a database.  It's not
built to support searching for data - such as looking in place A and
then trying place B.  You can do this, but it's rubbing against the
best way to use the DNS.

You can't get a 'wildcard' in a response unless you are doing zone
transfers, dnssec or the like.

You're misusing the terminology.  You don't get a wild card in a
response.  Wild card records are in zone transfers, DNSSEC has no
bearing on the issue.

PS - I'm still catching up on the thread, but I have to say that wouldn't all this go away with a new RR type? The new RR type could then be used at an explicit name or in a wild card record. The whole issue of prefixing names, looking around the tree, etc., dissipates.
