    Right. But even if client certificates are used, these are only used for
    authentication (signature check) and not for encryption during
    master-key negotiation.

    That issue is something I have on my mind ever since Michael Warfields
    discussion about this in Focus-IDS. I'd like to remember that issue for
    comparisons between SSL VPNs with other type of VPNs (IPSec or SSH) as
    these do not have the same ...uhm... weakness. I still think people put
    too much stock in SSL VPNs.

    Oh well...
