Why would you want NAT66? ICK!!! One of the best benefits of IPv6 is being
able to eliminate NAT. NAT was a necessary evil for IPv4 address
conservation. It has no good use in IPv6.

NAT is good for getting the return traffic to the right firewall.  How
else do you deal with multiple firewalls & asymmetric routing?

Yes, it's possible to get traffic back to the right place without NAT.
 But is it as easy as just NATing the outbound traffic at the
firewall?
