Hm...  might one not want to track the certificate, though?  If it's
changed, then there might be shenanigans.

But if the attacker can generate traffic with the trusted public key,
the site would have larger problems than with the certificate, so
perhaps it doesn't add anything much security-wise...

Does gnutls have a function to fingerprint that info?  Or access it in
raw form?  I guess we could just sha1 it ourselves.
