Simplicity is not always best. Think about how many people complain

A good suggestion. It looks like I will need to run a series of 
experiments instead of just being able to convert my existing scenes.

Bah! Kiddy stuff. :-P
It is generally with meshes that I have been using it with.

That is fine, Chris sent me an evaluation copy to test. :-)

That is good.

That is understandable. A totally black surface will not have any 

hard to imagine but what do I know? ?_?

It is easy to notice if you have forgotten it. The render is too fast. :-)

What I really wanted is an understanding of what the translucency values 
mean in RL.
To my way of thinking a value of <1, 1, 1> would mean that the material 
is completely translucent and all the colour components are allowed to 
penetrate unhindered. Why can we use a value > 1?

Yes some experimenting is needed.
