AFAIK one (and hopefully only) problem is with very small objects, or 
camera that has small angle,

Ofcourse using _huge_ object could result in lost of precision and out of 
double range errors, and AFAIK using objects with details < 1.0 could lead 
to some shadow problems.

Btw, there fore I think it is best to create scene in with typical object 
has about 100 units (like we create a model of ufo - start with sphere{0 
100}, model of a room - box{-50,+50} and so on), and in with no datails are 
smaller then 0.1 (with room example - if YOu are planning later to zoom-in 
on some objects like cofee mug, or computer monitor perhaps start with 1000 
unit room).
