Internet in a can?
What is Librarybox? It's a low-powered wifi router that can be run from a solar panel, battery or even a bicycle charger. It sounds like an interesting "work around" for lots of applications - it can be purchased for $150 and the source code is available for free - great was to create a private LAN.
