I wonder if it might be possible to break the scaling in such a way as 
to have one's cake and eat it too...?  What just occurred to me was the 
sample "Desk" scene, which is rendered as a three-frame animation in 
order to create a recursive image in the photo on the desk.  For example:

Write the scene as a two-frame animation.  When frame_number = 0, render 
only the very distant objects, with one POV unit = a very big number. 
When frame_number = 1, render the closer objects with one POV unit = a 
smaller number; use the output from the first frame as an image_map 
applied to a plane or box in the background of the second frame.

By putting actual, legitimate scaling factors into your code, you can 
therefore argue that you haven't "broken" the scale at all, but merely 
dragged it, kicking and screaming, into the real world.

I think this would work, but I've just barely finished my first cup of 
coffee...  ;)
