That's interesting... I don't know if it's possible to animate directly on a bezier curve, though that'd be an extremely-useful thing to be able to do.
It looks like all the animatable properties just have ease-in / out timing, and go from A to B. Given that, the best you could do is animate each X/Y direction's behavior, creating a new animation at each bezier curve point, and using the bezier form of the timing function to mimic curved paths.
