@uranther @kinsey @sireebob @dogoken In remote regions of the world, Internet traffic does, indeed, travel by foot. People have bus routes, and they equip the buses with wifi routers. Remote towns accumulate packets until a bus w/ wifi arrives, and offloads traffic at that time.
You need specialized client software to make this work (more like BBSes or UUCP back in the day), but apparently folks do use it today. I hadn't known.
