Sure, it might turn out that embedding GPS receivers in every munchkin is cost-effective, but it also might turn out that it's not. Right now they seem to command a considerable price premium, in the tens of dollars --- about one and a half orders of magnitude greater than the price for an entire munchkin. I don't have any idea whether radio receivers' costs will start to obey Moore's Law, but I don't have strong reasons for thinking they will. > I wouldn't also limit this to just direct neighbours, a node can > sometimes see quite far -- but you'd get other distance metrics, > such as signal strenght or a relativistic pingpong measurement. Indeed, I was only starting with a grid and eight neighbors because I figured that if the approach would work anywhere, it would work there. While visiting Darius Bacon a couple of weeks ago, it occurred to me that, at least for a regular two-dimensional grid, an Ising spin glass simulation (per bit position) is probably the right thing --- it can evolve arbitarily large domains in relatively few iterations.
