This looks like a really nice device, and some of the accessories look interesting too. Their evaluation card ("modEVA Main") seem like it might be a good basis for a USB colorimeter.
The "modEVA TOP" looks like a reflective colorimeter setup.

Of course, they may not be very interesting in selling these one at a time to hobbyists...
