Interesting that this was posted shortly after the discussion about developing on handhelds prompted by RFS5. The hardware used by the MIT system, excluding the projector, is mostly provided by mobile devices these days anyway.
There could be an interesting way to take the RFS5 idea and combine it with an approach similar to this. Targeting developers in that case would be a smart approach since they're more likely to be early adopters.
