Yes, I think there has been some ISP/Manufacturer working group to get this cleared up and defined. My ISP waited with IPv6 rollout until this was resolved, and the router they deliver does exactly what you describe above.
Yes, good solution
When IPv6 was designed, the idea was still that every host should be able to communicate with every other host. That has proven to be a bad idea on an open network, so IPv6 had to be crippled to make it viable. But that at the same time removes one of the major incentives to roll it out, as NAT can be used as an alternative solution in most situations. Many places have still not started IPv6 rollout...
The reason I prefer IPv6 over IPv4 NAT is it gives me the option to use the same ports on multiple hosts on my network. IPv4 NAT is quite crippling for some of ujs (who also happen to know how to manage our firewalls ;) ).
