I think Tim's point is that the only realistic options are:
i) IPv4+NAT
ii) IPv6 without NAT.
The IPv6+NAT option makes little (no?) economic/technical sense - it has all
the operational downsides of IPv4+NAT, plus to which you have the cost/hassle
of deploying v6.

We aren't *ever* going to give everyone PI space (at least, PI space in
whatever namespace the routers use to forward packets), any more than we are
going to let them take their street addresses with them when they move.
Routing (i.e. path-finding) algorithms simply cannot cope with tracking 10^9
individual destinations (see prior message).
