True enough I suppose.  Then you could always just use a clipped plane as 
a single face of a pane of glass, and fake it.  (the great maxim of 
computer graphics as far as I'm concerned, if it's too tricky to do the 
real way, fake it.  <grin>)

Although thinking about it, assuming that both textures were identical 
apart from the reflection settings (Interior etc.) then surely the non-
reflective face would work to kill any TIR that might be taking place?

I'll try playing with it tomorrow night, as I need to hit the shower and 
get to bed since I'm knackered.

Bye for now,
     Jamie.
