KioskNet
KioskNet is a system, developed at the University of Waterloo, to provide very low cost Internet access to rural villages in developing countries, based on the concept of delay-tolerant networking. It uses vehicles, such as buses, to ferry data between village kiosks and Internet gateways in nearby urban centers. The data is re-assembled at a Proxy Server for interaction with legacy servers.[1]. The system is free and open source.
