It is a basic principle often used in both protocol design and ethics that one cannot endorse a course of action that, if all were to follow it, causes undesirable consequences. If NAT is really the future, we must prepare for a world where NAT is carried to its logical conclusion; all sites use NAT. If that ultimate future is undesirable, then we should not even start down the road; we must conclude that NAT is not the future. It can, then, be at best an expedient hack. If we accept that peer-to-peer communication is a design goal of the Internet, then to make a convincing argument that NAT is the future, you must outline how two sites behind a NAT can communicate with each other conveniently. Otherwise: "That does not scale." -- Shields.
