After a half serious post to the IETF list I decided to write a quick
draft about the following:
Abstract
This document describes an extension to the mechanism outlined in RFC
2765 that allows IPv4 hosts to communicate with IPv6 hosts through a
protocol translation device with full IPv6 compatibility.

Thanks for this, Olaf. Indeed, we are considering follow-up work,
and understanding the scenarios & possible need for producing
a revised version of NAT-PT is on the Vancouver agenda (currently
planned to be a discussion in V6OPS, with protocol work to fall
out to an INT area WG).
In my opinion we have to be very systematic about this. The only way
that we can avoid the intrinsic problems of stateless translation
seems to be to have awareness at the IPv6 end that translation is
happening. (The underlying problem is how to reach legacy IPv4
hosts, who by definition can have no such awareness). That seems to
mean getting rid of the "less" in "Stateless IP/ICMP Translation",
so I think we need to go back to basics. I don't have any specific
proposals in mind, but I'm pretty sure that signalling between
the translator and the IPv6 host will be needed.
