v6 & DSL / Cable modems [was: Private use of non-RFC1918 IP space (IPv6-MW)]

Wii should not even consider developing " a cool new protocol for the Wii"
that is not NAT compliant via V4 or V6. And if they do, we should elect a
NANOG regular to go "POSTAL" and handle the problem. The solution to many of
these networking conundrums should rest with the application people, and NOT
the network people.

While I am ranting, my other pet peeve are proprietary protocols that the
developer cannot take another couple of hours to provide a decoder for. If
you develop the protocol any of the developers at the Wireshark group would
help with the decode plugin.

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?
