Just show me how to do IPSEC AH via NAT. Or how to connect to a
service that does RFC1413 ident lookups and actually does something
with the returned value.
Even trying to have a mail server HELO with the right host name,
regardless of whether the machine connected to is on the internal or
an external network, is a challenge if NAT is in the game.

IPv6 _IS_ this much better solution.

Then you have not tried a lot of things.

You're trying to be washed without getting wet. IPv4's fundamental
problem is too small address space. IPv6 is simply just IP with longer
addresses. And it is very compatible.
This whole thread sounds like you're desperately trying to find a
problem for _your_ solution because you're afraid to learn something
