I've been reflecting - would #sneakernet be more popular if it were easy? In my post at https://changelog.complete.org/archives/10421-dead-usb-drives-are-fine-building-a-reliable-sneakernet I describe one way to make it easier: NNCP with reliable wrappers (so a dead USB drive or whatever doesn't mean data loss). Here are some scenarios where I think through situations it might be useful (a thread):
@jgoerzen I kicked around a project that would use reusable mailable USB envelopes. You can fill in the banks..
@joeyh Interest piqued! I thought of SD cards because, even in protective holders, would be really flat. I don't know if quite flat enough to avoid the "thick mailpiece" surcharge, but I imagine a person could come up with various protective-enough and thin-enough things. Curious about how you envisioned that going! always closed, USB ports on the side or something?
@jgoerzen I've mailed thin USB keys in envelopes, and they were fine with regular postage.. even international (10+ countries)
I used cardboard inserts with a gap for the key.
I have somewhere a folding envelope prototype, the idea was it unfolded to plug in the key, and there were two configurations that exposed either of two sets of addresses, to bounce it between 2 people. just add a stamp each time..
@joeyh Oh very nice! Would those be ones with sort of a "half connector" like this https://support.yubico.com/hc/article_attachments/360011813840/YubiKey-NEO-1000.png ? Or maybe there are really thin USB-C variants these days.
@jgoerzen yes, very much like that
