>Collect all student assignments in a database and routinely re-run them through the most up-to-date cheater-catching software available. Anyone who gets flagged, even years after graduation, gets their degree revoked if they don't make an adequate defence to the university.

So if some new overhyped plagiarism detection system spuriously decides that I cheated years ago and I've long since thrown away any notes that might show otherwise, I lose my degree? I don't see how that's a good idea.
