I want to do a strange effect with a normal looking person casing a demon
shadow on the walls as she walks past.
I was thinking one way to do this might be to have a series of dark
(negative) lights projecting 'through' the object (wings), without the
object (wings) being rendered.
Any other ideas?

Use no_image and no_reflection on the shadow-casting object. Wouldn't that
suffice?

and perhaps also no_rediosity and photons passthrough?

With no_image and no_reflection, radiosity won't touch the object anyway,
but you're correct about the photons, they need to pass_through.

Don't forget to put no_shadow on the visible object, or you get two shadows.

But no_shadow means no highlights either, doesn't it?

Not at all. The highlights are a function of the brillance and the specular or phong
in the finish.
The only thing, is if the subject get self shadowed, it wont'cast shadow on itself. At
the same
time, the no_image one will cast shadows on the main subject.

The confusion may come from the fact that using shadowless in light_sources
does indeed mean no highlights.

Oh, yes... that was it!
no_shadow -> no shadow
shadowless -> no shadow, no highlights
