Well, just because you haven't found a way to do it yet doesn't mean it can't be done. From what's on these forums there are ways to draw the shadows. There just isn't an example made yet to test if an object is in shadow. As a simple idea the line of sight behavior could be used from the lights to the player and if there isn't a LOS then the player must be in shadow. There are probably other ways though.
