It may require a certain amount of rethinking your methodology, but, I have yet to encounter an application where you could not achieve just as good a result without NAT using better methods available in IPv6.

I'll take you up on that. Solutions presented must not rely on a third 
party tunnel broker.

1. "Dual-WAN router". I have a dozen PCs on people's desktops. I want to 
use whichever of my two ISPs is currently up and running, noting that 
either may fail at any time. The PCs are running XP SP3 and you may not 
change any software on them.

2. "Intranet". I have thousands of PCs on desktops across a 
multi-building campus. I have all sorts of internal servers that have 
static IP address assignments that I need to reach from these PCs. I 
don't want to renumber anything or even reconfigure my DHCP servers when 
I change providers.

I know how to solve parts of each of these without NAT, but I can't find 
any case where the solution is "better" when you don't use NAT... so 
list how you'd do it.
