I have been using the grid (with student numbers) on team folders for years. Since the number system is a reasonable strategy to ensure privacy, I do not considerate it to be in violation of any privacy guidelines or regulations.  I do, however, explain the system and why it has been set up that way.  I have never had a single complaint from a student.  In fact, my sense is that students appreciate the efficiency of the system while paying attention to their privacy.
