More stringent hardware based input systems are likely non-starters due to ADA requirements. For example, disabled students have their own input systems and a college will have to allow them reasonable accommodations. Then there's the technical challenges. Some authoritarian minded schools might try this route, but I hope saner heads will prevail and they'll be able to re-evaluate why take-home work exists in the first place, and whether it's actually a problem for students to use AI to augment their education. Perhaps it isn't!
