Is there anything that enables key exchange via smartphones? Ideally it should be as easy as a meatbag handshake.
Basically, if you can swap contacts via NFC then the pgp keys should go along with it.
It may have some theoretical weaknesses such as the exchange being MITMable if the users don't verify something on their screens, but I think having many more edges in the graph would make up for it since you might already have an expectation for that key through friends-of-friends paths.

- NoGravitas 10y agoTo expand on this, OpenKeychain wants you to use the camera on your phone to scan a QR code on your friend's phone.
