One thing puzzles me though. I would have thought the Curve Param constraint could do what I have needed many times, ie constrain an object so it could move freely along a spline driven by something else by its other end, so to speak. Like a rod with a ring at the end hanging from a wire - you can pull the other end of the rod and it will only be able to move along the wire.
I guess this requires a more complex system where the curve parameter is somehow driven by the object that drives the animation.
