Nice - I've written something similar for private use in the past.
The main reason why something like this isn't in sshd already is
that I haven't reworked it to handle multiple authentication.

As of last week, sshd keeps a list of the user public keys that were
used in authentication. This should make implementing the pubkey bit
of this easier...
