I haven't been paying attention, but has eyetracking software gotten that good? Can you point to people or companies who are working on this, or currently available solutions?

I've been doing some usability testing stuff and it'd be nice to have eyetracking (especially paired with click/mouseover data.) and not much less helpful head/face tracking that is built into the webcam.

GazeHawk (YC funded) is, but the software isn't open.
