[messaging] Encrypted Pulic Contact Discovery

This is similar to the decentralised identity service ideas we've been experimenting with for Matrix. The problem we've hit (which I think this scheme suffers from too) is how you choose which auth providers to trust, otherwise you end up un-decentralising the system as the defacto auth provider ends up with way too much power. Do you consider this a problem?

We've been looking at using something like the stellar consensus protocol to propagate trust/reputation between the auth providers - or limiting ourselves to email and piggybacking on top of DKIM like webfist/webfinger.

p.s. does anyone know how dead/alive webfist is, and whether/why it failed?
