Do you need a special license for tobii 4c to use/develop this kind of software?

@trishume sorry to bother you, i just saw tobii 4c available to purchase, and I am wondering if it is possible to make it work on linux?
In some places on the internet tobii company says i will need to buy some special upgrade pro key for their research license.
Did you?

I am not the author, but I tried to get eye tracking a la FusionMouse to work on Linux, and can tell you that Tobii has no interest in supporting anything like that. Avoid them.

I used an early access build of their API, they probably do charge a lot of money for it now.
