I'm not sure if you saw, but I did bring up the idea of using a PAM module
earlier.  I do think it's possible, as the PAM system has a pretty general
idea of 'conversation' in its process of performing its actions.  I even
found a sample where someone implemented a CAPTCHA-style PAM quiz module
that would ask you a series of simple math questions to ensure you weren't
an automated script.  It was really rough, but seemed to demonstrate that
the idea could work.

Getting a usable interface between the PAM module and the
quiz-administering program could be tricky, but it seems very doable for
someone with the inclination to do it.
