“OK,” you’re probably thinking. “John, you talk a lot about things like Gopher and personal radios, and now you want to talk about building a reliable network out of… USB drives?” Well, yes. In fact, I’ve already done it. What is sneakernet? Normally, “sneakernet” is a sort of tongue-in-cheek reference to using disconnected storage to transport data or messages.
