Found this during my daily visits to gamedev.net: http://www.gamix.org/ This Pennsylvania based company is trying to make an open gaming platform. It has some interesting specs so far. Sounds like an interesting endevour. I'm not jumping on the bandwagon nor promoting the platform. Judging by the activity on the forums, there are a lot of questions seeing as it does not favor an API nor a specific OS. However, I figure it's something worth investigating, seeing as their targeting indie developers.
