[messaging] Audible public-key fingerprints

Hi everyone,

With regards to the question of more usable public key fingerprint
verification, I propose that a device (especially mobile) emit an
audible encoding of the fingerprint, which the second device decodes
and checks.

Almost everything has a microphone and speakers, so verifying a
fingerprint would involve bringing two devices to within a reasonable
distance and letting them speak to each other.

Does that sound like a solution?

If so, I'll try to share a proof of concept next week.
