the problem you may have is that there is no transparent path right
through the object.  one idea is surface texturing.  i think there was
something in the megapov docs about it.  thant would give you a texture
on the surface with a hollow inside.  speaking of hollow, i know hollow
is needed for media to be visible, but i don't know how or if it affects
objects with textures.  also, as an experiment, try starting with a
totally clear sphere and adding each layer one at a time so you can see
the effect each has to the overall transparency.  remember that the top
layers need to have the most transparent areas so the bottom ones can
show through.
