The main problem with NAT is protocols that embed IP addresses. I don't 
think many protocol implementations can be changed by a search and 
replace like operation, the same way simple apps can.

NAT doesn't work for MANY things by default. You have to add stuff to 
make it work. If this stuff isn't added for IPv6, your IPv6 NAT will 
only work with simple client/server apps.

Also: what is the point? If you're going to do NAT anyway, why bother 
with IPv6?
