I know that.. I've NAT'd some very large networks with full mapping from 
Network A IP's to Network B ip's.. All public IP's. I built ASN-3901, and 
help build several other ISP's. Renumbering was a specialty of mine for a 
while. I don't do much networking anymore.. I'm rusty and haven't followed 
the IPv6 trends since 2003 when I cared deeply about such things.

In the common every day small office or home. NAT is PART
of the overall strategy of network configuration.
You made a startling (to me) declaration that NAT is essentially DEAD in 
IPv6 and we would run public IP's into our home and office network.

What replaces the common current practice of a private address space
(192.168.x.x typically) being used internally for business and home use?
Surely we don't run it all wide open and public.. or at least, I won't be.

Even so, I still treat my internal home and office network as hostile.
Old habits die hard.
