Wow, you people write a lot . Not read the thread, but to answer the question:

Joozey: Wicked. How "simple" is it? Like, can it be used for any surfaces? Or just straight surfaces? Any Demo video of a character walking (or just moving) around using your 2d collision?
Well fairly simple, of course it needs to be programmed from scratch (though I saw someone contributed a 2D physics package, not looked into it yet though). Surfaces can be curved, but the more accurate you want it, the heavier it gets for the CPU (I'm personally not that good in optimisation).
