Hmm, are you using MegaPOV? If so, you might want to check out the glow
patch. It might be a good alternative to media for this.

Yes. The appearance of media is determined by the distance you see
through it. If you scale something up by 2, everything will appear twice
as bright, shadows cast by scattering or absorbing media will be twice
as dark, etc. because there is twice as much media between any two
points.

You can have as many containers as you want, they are just ordinary
objects. Are you making sure that all the containers have "hollow"
specified and are not in any non-hollow objects?
