What's the difference to firewalling without NAT? (Noone should connect 
their (home) network without at least inbound filtering) There I have to 
wait for the firewall box to support connection tracking for the new 
(broken) protocol.

If the end-users really get public addresses for their WII and game-PCs, 
do you really think they won't just open the box totally in their 
firewall/router and catch/create even more problems?
