Without testing this (I have a large slow render running at the moment),
I hereby add another
plausible method to generate shadows without an apparent casting object:
difference{
object{MyGhostCaster}
sphere{<0,0,0>,10 no_shadow} /*chosen to contain the GhostCaster*/
}
If this works as I think it will, the sphere will completely annihilate
the object, but
be omitted from shadow calculations... Anybody want to confirm this?

Doesn't seem to work. Too bad.
(Or I've done something wrong)

Bother, you're right. <grin> Well, it seemed like a good idea at the
time.

I have another idea that might work : use the "passes-trough" feature
in Superpatch with a NEGATIVE (White*-1) light, it should do the
trick...

But that's cheating. That feature was designed to produce unnatural
lighting effects.
