Unfortunately, framerate independence would need a change to the way the
demos are coded, no more dWorldStep(0.05f), the system that I use in my
dynamics stuff (http://www.cersoft.com) double buffers the position and
orientation quaternion, these are then used to update the display
position and orientation at the required time.

I'll have a think about it ....
