These use-cases still do not qualify. The security concerns described
are related to HTTPS in this paper, and they extend to all other
protocols. Corporate smart card implementations might be a different
story, but then again, you've got your own X.509 infrastructure within
your company and do not rely on external CAs (or at least I would never
suggest a customer to do so - it simply does not make any sense).
