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.
