to the extent this is true, it's only because the only applications that people become aware of, are those that can run over NAT. many more useful applications exist, but since they can survive only in less restricted environments, they aren't as well-known. > Granted, it's easier to talk about the evils of NAT than to explain how > billions of new routable addresses are going to be added to the existing > routing system. if you're willing to constrain those billions of addresses to use a single path to the net (as NAT does) then the existing routing system does just fine.
