Just to add another topic into this thread, do we think the DNS is the
appropriate place for this type of decision to be made?

There is certainly precedence if this is taken as an extension of the
DNS "views" concept. However the argument can be made that this is
better handled  by not doing it in DNS, but instead handling it at the
endpoint that pops out at the end of DDDS processing. If we ignore
re-targeting and evilbox manhandling of the messaging we need to
transmit the same information anyway correct?

I'm in the DNS camp for what it's worth, since the protocol is to my
knowledge lighter/faster and generally more efficient for these types of
stateless queries. However since this would add URI parsing and possibly
crypto elements into the mix I reserve the right to change that opinion ;).
