>IPv6 will re-establish the peer to peer nature of the net and will (hopefully) get rid of the biggest stumbling block to launch the next level of application: the NAT (the biggest kludge on the net aka a poor mans firewall). We can hope. But I'm not optimistic. Legacy kludges like NAT have a habit of sticking around for a long, long time. And ISP have come to rely on NAT basically -- like you say -- as a firewall for their less technically-inclined customers. It's too bad, IPv6 could have opened up a world of p2p apps.
