my university acquired one this past fall. Not sure if it was donated (probably) or the CS department just decided "we want one" and got it.

Right now, it just sits in a corner on the third floor of our CS building, waiting for people to come buy and play chess or whatever. It's not used much.

I think projectors with sensors on the board are more likely to be mass-produced. I've been seeing them since 2007 at the latest.
