I know I'm new here, but I could I propose that we give it two weeks (just to make sure we allow for the possibility of spring break, and we assume that something this simplistic wouldn't be a multi-week assignment), and then see who can come up with the most creative solution, that meets all of the requirements, and yet would still fail spectacularly under realistic conditions. (and you've already suggested at least one failure scenario, but there's just sooo many more.)
