The slowdown depends on how expensive the intersection test for the
container is - but unless you use an extremely slow isosurface or
similar it is unlikely that this is considerable compared to the media
evaluation - there are no additional media calculations necessary with
this technique.

The place is sample_media() in media.cpp. As it is you don't have a way
to determine if the evaluation is in a radiosity ray or not (the
NO_RADIOSITY_PATCH in MegaPOV provides one though).
