Just for sake of kickstarting the discussion..
I have no experience with EyeGaze, and what I have seen of it is really basic, kind of one-finger typing.
You should take in account that Maya not only uses many key + all mouse button combos, but also it requires pixel-precise movements. I guess, there will not be *ALL* Maya features, rather some limited ops. Some freedom might come with knowledge of MEL. Perhaps some UI/HUD can be programmed to manipulate the viewport. Need some additional brainwave sensing, which is future for now. Best of luck, guys!
