I think that is probably the solution. I've seen somewhat similar systems that tried to be more technically advanced than that, but they always made things worse. Just a straight-up camera-feed to the projector would work great though.

The advantage of these over overhead projectors would still be pretty small though (really only the being blinded and replacement bulbs issue), so you would need to ensure that the system is rock-solid reliable. If not, then you've just made it worse by making it more advanced.

Document cameras like this work very nicely, but there is one small downside I've noticed: their framerate tends not to be very good. That's usually not a problem at all, but I have a couple of physics demos where I roll things around on an overhead projector, and the document camera often can't keep up with quick motion. Simple analog light and shadows obviously have no issues with that at all.

overhead projectors are a bit dimmer and can't make nearly as big (or uniform) an image as the document cameras can.
