Check out no_image, no_shadow and no_reflect.

Also, if you're shining a spotlight on the thing and expecting to see 
spots of light all over the place, you'll be needing photons to do that. 
What you could do (not sure if it will work properly) is run POV-Ray 
once with the object there as normal (to generate the photon map), and 
then run POV-Ray again with the same photon map but with the object removed.
