I was a bit disappointed until I read the bit about hardware hack-ability. Accessibility in games is an oft ignored topic. The open nature of these controllers will hopefully lead to more games being playable by disabled gamers as people extend the hardware. Of course, the flip side of that coin is people modifying the controller to gain an unfair advantage.
Very true! When it releases, I may try to use data from an Eye Tribe (http://theeyetribe.com/) to drive the right trackpad output. The added cost seems like a valid deterrent against people just trying to cheat, and a bearable cost for someone who wants to play games but is incapable of using a traditional controller.
