I agree, the security benefits are welcome. In my IPv6 network mr. router applies security in much the same way as a NAT-IPv4 router does.
Which ruins any end-to-end benefits that IPv6 was going to give over IPv4, right? (ie. SIP, etc. won't work, unless the router knows about it)
So, why are we caring about IPv6 as a means to preserve end-to-end IP, if moving to IPv6 means we don't really get it either?
Proxies etc. can be deployed, and be working for everyone (save a few corner cases, perhaps), right now. They don't require any global switchover/upgrade/etc. and on top of that, they can be used as extra revenue streams/products/etc.
If everyone had one computer (network enabled device) behind one NAT device your statement may actually start approaching truth. However, as is becoming increasingly common, this is not the case. Please play again :-) -- Steve.
