Yup, that's how it's supposed to work.  I tried a spotlight and can't get it
to work very well.  It appears BMRT has the advantage of calculating true
area lights instead of just doing shadows.  I tried hacking the POV code to
produce an inverse square falloff to the lights and it appears to work, but
as you can see it's quite different from the BMRT image.  I'm still thinking
of working it in as an option for lights.
