Should NAT become prevalent and prevent innovation because of its limitations, this means that innovation will happen only with IPv6 which means the next "must have" viral applications will require IPv6 and this may spur the move away from an IPv4 that has been crippled by NAT everywhere.
It won't happen and I'll tell you why not. Client to client communication block diagrams: Without NAT: Client->Router->Router->Router->Router->Router->Client With NAT: Client->Router->Router->Relay->Router->Router->Client At a high level, the two communication diagrams are virtually identical. Add killer app. By it's nature, a killer app is something folks will pay good money for. This means that 100% of killer apps have sufficient funding to install those specialty relays. Odds of a killer app where one router can't be replaced with a specialty relay while maintaining the intended function: not bloody likely. Regards, Bill Herrin -- William D.
