IPv6 also has a class of single per-machine addresses that are sent to
the most convenient interface, so that might get rid of multiple IP
addresses per machine. NAT has _perceived_ security benefits, so not
much chance of killing that.

Service/port tuples; well, I disagree, but no doubt if I argue the
