  Perhaps a patch could be made for this purpose. It wouldn't be realistic,
but it could be used for this special effect. It certainly has its uses.
It would be like an advanced drop shadow effect (like the one in most
image manipulation programs, but a lot more advanced in the sense that
the shadow can be "dropped" onto any (invisible) surface, not just
a plane facing the camera, like in the image manipulation programs).
This in conjunction with area lights would make very good effects for
transparent pngs.
