Sorry, I wasn't able to follow all the discussions recently, so my 
comment may have come up. Instead of standardising units why not require 
a "small scale object" to fit in a centerd 1x1x1 pov-unit cube. Then any 
user can scale the object to fit in a scene. For large scale objects one 
could recuire it to fit in a 100x100x100 unit box. Or require that the 
container for every object is defined in the #includefile (eventhough it 
can be figured out using min/max_extent)

Thanks for the summary Chris.
