Interesting, but I'm not sure how it would work for AH.
For racing games, sure, the important stuff is all in the center of the screen.
Whats in the corners is really not important.
Same is not true for AH though.
I understand your point - I just want to mention that you cannot get a real sense of how the screen works by watching a video.
I don't have one either, but it was immediately obvious to me from watching the posted youtube video that the very fact it is recorded and then reprojected onto a flat monitor distorted the visual feel you are supposed to get from such a system. I would have to try one in real life to be able to judge its suitability for AH.
Note: the roughly spherical-flat projection distortion is why we have IMAX and dome screens in the first place; it's supposed to "look more real" because such domes are closer to how we actually perceive the world than a flat screen is. I'm not an expert, so correct me if I'm wrong on this point.
