Couldn't that be done by some Python script? I remember, many, many moons ago, 
that there already was a technique to do this using dupliverted spotlights 
and for example a circle path or a subdivided mesh. This was easy to set up 
and handle and could even track other objects (just make the circle TrackTo 
the desired object). The diameter of the circle would influence the softness 
of the shadow.
