You can add interior media etc to any mesh, but the results might end up
garbage depending on the nature of the object. If a camera ray only passes
through one surface on the mesh, for example, then the media will appear
saturated. As long as the mesh is a fully closed volume, media should work
fine.
If an inside_vector is added to the mesh def, CSG is also possible (provided
the surface normals are also consistent).
