Revocation is interesting, because it's basically a message which is
signed but not encrypted: the sender is a specific person, but the
"recipient" is the whole world.
I guess it would be similar to the current system: you prepare that
message in advance and sign it. If you lose access to your old
address, you get yourself a new one and send out the pre-prepared
message saying that you've lost access to your old address.
Essentially, keys and addresses serve a similar function: both are
"online identities". Keys are used by the cryptographic systems to
identify you, while addresses are used by the email server (and
routing system) to identify you. I think it makes sense to combine the
two.
