Well I was thinking of exporting at first, but it's too fraught with
problems. I would in general like to see more use of persona
signatures as certifying keys as good enough. Essentially I see the
requirements for certifying keys as a massive barrier to entry for
common use.

Greater integration of local signatures into mail clients would be
great though, essentially you could use your public key ring as an
address book. Currently none (AFAIK) even offer the security of the SSH
known hosts file of ensuring the same key is used as from the first
