I have been wanting to create something similar for years. Before I had access to the Internet, I used "packet radio", a CB-radio based network (there were/are amateur radio band versions too). The whole Netherlands, as well parts of Europe, were wireless connected (at 1200 baud) and one could send messages via the network of nodes from one side of the country to the other side, usually within days. Or chat with people one could contact directly (usually within ~10 km iirc). At that moment I didn't realise how awesome it was, but in retrospect it was pure self-organised anarchy, without any commercial or governmental interference. Regarding this AirChat, it is sad that they, as it appears to me, did not make usage of the expertise from the amateur radio community. Still, I believe that it has potential.
