It'd probably just be a TA turning on a video if the college is, at all, set up for modern learning. It's actually a really good solution and I'm surprised they haven't done it - ... Banning it kinda sounds like a college being a bad college for the professors. (You can be prestigious and also bad, in fact, it seems like the industries people desperately want to work tend to have the worst work cultures, so it wouldn't surprise me, e.g. zoos (basically zero pay) or the game industry)
