Making a light shadowless is quite simple, just add shadowless:
casting shadows:
light_source { <90, 12, 20> color rgb 0.5 }
not casting shadows:
light_source { <90, 12, 20> color rgb 0.5 shadowless }
Remember that this only influenceses the shadows that will be casted on the
floor ot other objects. If you shine a shadowless light on a sphere, the sphere
still have a dark side where no light reaches (which is also called shadow).

Good tip! If possible print out the POV-manual and read it 2 times, do the
tutorials and read the manual again. It's fairly basic and well written.
