I think the most flexible way would be to have some kind of 
"interaction_group" that covers lights (including highlights), 
reflection, refraction, etc...basically "this object only reflects this 
group of objects, and only has highlights from this group of lights". I 
think radiosity would still have to be a separate flag.
However, this would probably be too complex to use...it would most 
likely be simpler to use a shader of some sort.
