Please explain how you plan on getting rid of those protocol-aware plugins when IPv6 is widely deployed in environments with -stateful firewalls-.
You just open up a hole in the firewall where appropriate. You can have an ALG, the application or the OS do this. As you probably know by now, I don't favor the ALG approach.
End-to-end-ness is and has been "busted" in the corporate world AFAICT for a number of years. IPv6 "people" seem to think that simply providing globally unique addressing to all endpoints will remove NAT and all associated trouble. Guess what - it probably won't.
If you don't want end-to-end, be a man (or woman) and use a proxy. Don't tell the applications they they are connected to the rest of the world and then pull the rug from under them. This works in IPv4 today but don't expect this to carry over to IPv6. At least not without a long, bloody fight.
