I think the former is what is done on P3D and the latter is what is 
done on T3D.  (Just joking; I doubt that's true. 8-)  

You bring up an interesting point, though.  How come people can stand 
so much more total depth in real life than in a stereo pair?  I used 
to think it was because in real life you focus on the near stuff and 
the far stuff goes out of focus and vice versa.  But now that I can't 
focus any more, I wonder.  I also wonder if motion parallax doesn't 
help keep things sorted out.

The 1 in 30 rule for total depth from nearest to farthest object is
pretty conservative.  With the right arrangement of objects, you
can do much more in a stereo pair.  Bill Carter thinks you can do
much more if you let the too-near and too-far objects go out of 
focus.  From what I have seen of his stuff, I tend to agree.
