My solution was to look at the entire scene through a mirror and declare 
the camera inside a macro. You would give the mirror a finish{reflection 1 
specular SomeBrightnessValue roughness GlowSize} and place light sources 
wherever you want your glows to be. I made an include file but it was 
incredibly awkward and not very accurate (since it used a plane mirror). I 
might revisit it if Real Life would ease off for a little while.

I posted an animation of my system in action a while ago:
