SL 4: Moving a Bezier segment - use a transform?

Question

Hello,
In our Silverlight 4 app we use a Path with a single BezierSegment to connect two objects. When one of the objects moves, it is easy enough to change the appropriate end point of the path.
However, we would like to update the control points (BezierSegment.Point1 and BezierSegment.Point2) appropriately.
Is there a way to to use a Transform to good effect, or should we calculate new control points based on the new end point?

Thanks for any suggestions....
