Heh, I think this is moot for most network printers. Ie, I have an HP 4050 and know for a fact that the jetdirect card will never support ipv6 (unless someone publishes a custom ROM). So I'll need to run dual stacks or (more likely) have a router that does 6to4 for my printer. I expect most routers with ipv6 to do 6to4 native for old devices like my printer and older routers (can't wait for the cheap Cisco gear). Also, instead of setting port forwarding rules for nat, I think consumer will default to 'drop incoming connections' and you'll just allow per subnet, ip, port, protocol. Slightly different, but the same type of interface and general concept.
