Researchers at Intel Research Berkeley are working on way for remote people in developing countries to use the Internet and email: End users in a village without an Internet connection would write an email and hit send but the requests to send would be bundled and saved. When the bus, equipped with an antenna, travels through town, its antenna picks up all of those requests and also drops off email or even requested Web sites. When the bus reaches a bigger town that has a connection to the Internet, it exchanges information there.
The application sounds exactly like one being used in Cambodia but with motorcycle mail delivery people. That solution has been commercialized by First Mile Solutions.
