Yes, the demo has limits you get a popup at the beginning and the physX_run functions exits after around 20min. You are also not allowed to use it in commercial games!

OK about the price: I like you guys so I make a very cheap price for you. Although I was working hundreds of hours on this implementation... it will be : 15 EURO
This is the price for the basic version (any upcoming updates and tutorial levels for this version will be for free)

If everything goes right you can get it tomorrow (if I finished the manual tomorrow!)

P.S.: @rojart: I will check the problem with the PH_HINGE, the alternative is pXent_CreateD6Joint() with this you can easily create ragdolls.. there will be a testlevel/playground
