Using the light system and checking off the Cast Shadows, I was under the assumption that the objects themselves would cast a shadow and not block the light source. In my image here: http://chrisl.in/s/f401c7.png I setup a light source and set it to black to better explain but is it possible to reverse it so the light source is transparent and any of the shadows (for example the character has a 5 oclock shadow) would be black?
