This is not obviously going to work for v4 but I think is
one piece of a reasonably attractive approach. Conflating
reachability and routing has caused some real problems. But
when we look at stuff like VoIP applications it becomes
reasonably clear (at least to me, but obviously I'm biased)
that that sort of access device is still going to introduce
a heap of problems unless there's some sort of communication
with the host about what the host *really* wants (instead of
having the software on the access device make informed guesses).
Receiving end-to-end (i.e. unmediated signaling) telephone
calls is a good test case for whether or not these things can
work.
