You can cheat with some objects, such as bicubic patches, that allow
illumination from both sides.  I think MegaPOV lets you turn on that
functionality for any object with the double_illuminate keyword.

If that doesn't do what you want, your only alternative is a dense
scattering media.  The down side to that, of course, is that it might
be a bit slow.
