Keith,

Not going to rehash this whole argument we've had before. No one is talking 
about changing the fundamentals of how IPv6 or IPv4 work. They are talking 
about the technologies that are AVAILABLE to deploy as an OPTION in conjunction 
with IPv4/6. Your approach essentially boils down to... "Don't tell me what you 
want. I'll tell you what you want. Now shut up and like it." ..... Then 
wondering why you are having trouble getting folks to jump at that sales pitch. 
That approach may work well in boot camp...not so much in a free market 
economy... where people are used to exercising some level of individual choice.

End to end transparency is a goal that many organizations/individuals do NOT 
want.... at least not on all portions of their networks. If you can't accept 
that, then we are simply going to have to agree to disagree.

Regardless, nothing the authors are doing with this flavor of NAT (unless I'm 
mistaken about it) should break end to end connectivity between devices running 
IPv6 since it's a 1:1 stateless mapping. A FW with statefull inspection and 
packet filtering rules would...but in that case the person deploying the FW 
WANTS that connectivity broken. If you're trying to argue that people should 
not be allowed to deploy FW's.... well then, good luck with that.
