If you wanted to do something in the way of a peer-to-peer mesh, you could look at what was tried with the wifi on the OLPC machines. My impression is it did not work as well as hoped. One major issue would be battery life - you are spending your battery to move someone else's traffic. Granted wifi isn't designed to be as careful of power as cellular radios are, but it's an area where you can probably make the changes to get some functionality with merely a rooted device, instead of hacking undocumented radio firmware. To really build this system, you'll probably have better luck with specialized hardware - perhaps some of the long range zigbee stuff, or get an amateur radio license (not hard these days) and either do something really custom, or extend existing ideas. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
