A Transition architecture where neither ISP-NATs nor CPE-NAT64s are neeeded

[Rémi Després <remi.despres@free.fr>]

The following draft has just been posted.

It presents an approach whereby:
- The IPv4 to IPv6 transition period needs neither NATs in ISP
infrastructures, nor NAT64s in CPE routers (only NAT44s, plus an
address-port-borrowing-protocol similar to that presented by Brian
Carpenter in SHANTI).
- It also revives and improves the DSTM idea that duly augmented dual
stack hosts can establish pure IPv4 E2E transport connections (more E2E
transparency by augmenting the number of configurations where no NAT at
all is necessary).
