Bus.... Magic Bus!

From last week's Economist -- an old-school internet mail relay network using Wi-Fi and public transportation:

At “The Future in Review”, a wide-ranging technology conference held in San Diego earlier this year, Allen Hammond of the World Resources Institute, an environmental think-tank, outlined a cunning scheme to provide e-mail access in rural India using buses. Each bus would be equipped with an e-mail server and a high-power Wi-Fi base-station, with a range of a mile or so. This communicates with nearby computers in homes, schools, offices or post offices, delivering and collecting e-mail wirelessly as the bus drives past, so that there are a handful of deliveries and collections each day. The buses connect to the internet when they reach the depot at the end of the line. Given the reach of the bus network, it is estimated that this approach could provide national e-mail coverage for a paltry $15m. E-mail by bus—why not?
