XBox Live is regular, routed IP, that doesn't even need to much work to function from the wrong side of EvilConsumerBroadbandNAT. I guess the point was talking about original non-360 Xbox games, some of which supported 'LAN play' by hooking a lot of consoles together on the same local network. I have no idea what was sitting in the Ethernet frames that wasn't routable. Cheers, Tim.

I doubt that we will be deploying Windows servers in our network to route traffic. This is not the only way to do layer 2 over IP. See http://www.faqs.org/rfcs/rfc3931.html --Michael Dillon
