The Eye Tribe

Does anybody know an application for the Eye Tribe that can be used in usability testing?
Or maybe you know that someone is already working on this?

I mean that the application must be able to record a video from the screen with eye movement like Eye tracking software from Tobii Studio.

eyeproof from eyetribe do what you need, but is in beta for the moment, you shold ask them if they can insert you in the beta testing program to use it.
