Hi Guy,

Thinking more about this, perhaps the best solution for this problem is
to restrict IP's as much as is reasonably possibly. With a single
wildcard it is possible to deny all off campus students, and even some
campus students outside the classroom. Combined with a student sign-in
sheet that can be used to (manually) invalidate exams taken by students
not on signed in, one should have a managable solution at least for
small (less than 30 student) classes.

Thanks,
Lars.
