Oh, sure, I get that.  One of the problems I've had with the "end to
end NAT" argument is exactly that I can't see how it's any more
deployable than IPv6, for exactly this reason.  But the claim upthread
was (I thought) that the application _can't_ know about this stuff,
not that it's hard today.  Because of the 20-year problem, I think now
would be an excellent time to start thinking about how to make usable
all those nice features we already have in the DNS.  Maybe by the time
I die, we'll have a useful system!
