And when I drive someplace, I do indeed go by the signs I see, which are not erected by a central authority, as I move along.

Speaking about that, is anyone currently seeing geographic (local-knowledge) routing and authorityless address (=position) allocation from coordinates (e.g. WGS 84 position fixes) in any realistic time frame as a major component on the Internet?
geographic location doesn't map to topology
Presumably, one could prototype something simple and cheap at L2 level with WGS 84->MAC (about ~m^2 resolution), custom switch firmware and GBIC for longish (1-70 km) distances, but without a mesh it won't work.
I'm sorry, but I am very afraid of "Central Authority".
