After being stuck in various business decisions for quite a while, I can finally say that it has been open-sourced.
We finally decided to do this since it holds no value for anymore and it might inspire someone else to write eye tracker applications in Go.
Included in the examples folder is some basic applications we have had great use of for debugging and other et related tasks (including a console-calibrator).
I would be a shame if all this was forgotten, which is why I post it here, with the hopes that it will be of use to someone.
