Affordable eyetracking for Dasher sprint

http://www.tobii.com/xperience/ and https://theeyetribe.com/ cost around $100. Cheapest available medical eyetracker (PCEye Go $2000). Technically it should not be complicated. https://github.com/OptiKey/OptiKey has c# code translating these eyetracker input into mouse coordinates. Licenses are compatible. There is socket input allowing dasher to read coordinates from socket. I think this would be ideal, because eyetracking code would be isolated from dasher. Much easier to test socket server, than piece of larger software. You can use eyetracking now, but it is not ideal. We want raw data. No smoothing.
