The one that interests me is inspired by the Blackhat movie.
The premise here is that the donor has an app on their phone. They load their data into the app.
Then they go to a mall, down town shopping district, someplace busy and they walk around.
When they got home they see a green dot showing the data has been transferred.
Somewhere hidden where they were walking is a BT receiver. The app and phone sniffed it out and sent the data as they walked by.
Once the data is loaded onto the drop, it’s exported out via a mesh of LORA radios.
I don’t know how to get BT radios to pair automatically without ever seeing each other, even between cooperating parties. Or maybe it could work with WiFi Direct. Not really familiar with that.
I thought Briar could provide this functionality without any previous pairing using BLE? I don't know too much about BLE but you should be able to just broadcast data without any pairing. Could be encrypted with a pre-shared secret. If the payload is small enough, it shouldn't be that much of a problem.
Also Apple Wireless Direct Link is pretty interesting as well. It can do a lot more than Airdrop.
