I'll come back later after finishing a proposal of "end to end NAT", which has end to end transparency to be able to support ftp port command, SCTP, IPsec, DNS reverse look up, multicast, mobility and so on.
I have written an Internet Draft to explain end to end NAT.

You can see the only reason to deploy IPv6 to keep the freedom of end to end transparency is now non-exsitent.
Given that all currently available operating systems fully support IPv6, and none of them support the modifications necessary to "help the NAT gateway", I can't see how this would be a step forward. But this is far out of scope for RIPE APWG anyway - if there is consensus in the IETF that *this* is the way forward, then it's time for us to amend policies for this. Right now, it's a personal draft and one personal opionion. regard, Gert Doering -- APWG chair -- Total number of prefixes smaller than registry allocations: 128645 SpaceNet AG Vorstand: Sebastian v.
