NAT will not solve this problem; it resides at too low a level of the theoretical architecture, being used primarily to avoid renumbering of internetworks. This isn't a network numbering problem, it's a routing problem.Please, let's think this through carefully before making such pronouncements. If the problem to be solved is providing flexibility of choice, then Sean is quite right and NAT (plus other renumbering technologies) is the solution for most people. If you use NAT and renumbering technologies then you don't give a darn what your IP address is or who gave it to you as long as it is globally routable. You still have flexibility of choice in that you can switch upstream providers on a whim and use Paul Vixie's BSD tricks to multihome if that matters.
Ok; I've taken this private, because I'm only close to getting what you're saying, and my feet are too big. [ reads, thinks, chnages mind ] Oh. Shit. <thunk> Number the internal stuff privately and use NAT to renumber the external appearances when necessary. Fix the DNS when you do. Forgive me, all; I'm climbing back under my rock now.
