We either need a way to describe the special case of face pairs to the renderer, or these internal ray hits need to be done with a custom shader. I could see benefits of both.

I´m sorry but can you explain this a bit more for me? I´m not sure what exactly do you mean so it is hard for me to understad.

The problem is that "In the real world" works for this case, but not for all. What if there really was no gap, like in the case where a glass is filled with water with ice cubes floating in it? That's "in the real world" too, but won't be helped by this workaround. There needs to be a special way for this to be handled.

Actually there is a 4th way, and following the Pavel's examples it would consist on keeping the panels facing and remove one of the two faces.

"Liquid in a glass" sample is a bit like this, plus having to make some ior math, but results are superb.
This thread by Richard Annema should be very clear, and there's also a great tutorial on b2 manual.

But what of the absorption?
