Wiring up Bogistan (without wires)

Up at the University of Dundee they're working on a simple but boffinly idea: solar-powered street lights. Presumably some next-gen solar panels and heinously powerful LEDs or something, but they come with optional wi-fi and mains sell-back. The idea's based around the kit used by disaster agencies. Meanwhile Nicholas Negroponte is touting the $100 MIT clockwork laptop with mesh networking as a teaching tool for third-world kids. This is fab stuff. You could - concieveably - trundle a truck into a village in Bogistan and unload lighting, laptops, networking and enough spare juice to run a community fridge or two, all from the box and with no infrastructure requirements whatsoever. And if they use cornstarch plastics, existing materials to mount the lamps, and Honda's new non-silicon solar cells, the environmental impact might even be sensible. Add a point of presence to the internet and you've got a global hookup with reliable data, voice, and whatever else you fancy. I want a crate of goodies and an island. Please, Santa?
