Not planar mapping, spherical mapping. Distance would be z, and
vertical/horizontal angle would be x and y, and the center would be the
light_source position. It would be like wrapping the pigment around the
sphere, except the color also varies depending on it's distance from the
center of the sphere. You would have to tile it in some cases(many times
the tiling wouldn't be visible), but I don't see any other way of
mapping 3D space around a point. Maybe also cylinderical mapping.

That is an idea...although I guess it could also be done with scattering
media using the density file and a plain colored light, at least as long
as no other lights interact with it.
