I love the possibilities of sneakernet x Bluetooth mesh to circumvent censorship.

You stop at the coffee shop, get some groceries, or just walk around town visiting friends, and your personal relay fills with notes you don't have, while updating others with unseen notes from yours. You craft replies and make your own notes at home, to complete the cycle again tomorrow. All out of the view of the authorities, without your data being centralized on a faceless server somewhere, ready to be scanned, analyzed, and used to target you with advertising (or worse).

It's like something out of old sci-fi stories I used to read. It makes me want to buy some fashionable steampunk goggles 😂
