Radiosity is calculated by tracing rays in the scene, just like normal 
camera rays, there is no special handling of media for radiosity.  To do 
what you describe you would need the media sampling code to selectively 
increase the media intensity if a radiosity evaluation is detected. 
Doing this does not make a lot of sense.  You can already achieve what 
you want using the no_radiosity flag in MegaPOV - create one instance of 
your media object with stronger media and no_image, no_reflection and 
no_shadow and the normal one with no_radiosity.
