    Well, private key has to be encrypted with password and probably stored on
    removable media. Of course, it does not help if some keylogger (and a program to
    copy private key file) is installed by the intruder, OTOH it seams that in this
    attack scenario only some additional "device" can save you (e.g., SecureID or a
    printed list of one time passwords).
