FWIW, it would seem that Sawfish is already doing something like this.
Is moving this placement code into metacity a good idea for the generic
case? If it's only useful for nautilus then keeping the code in Nautilus
allows us to control our positioning on any window manager.

It would seem to some that Metacity's placement on multihead setups is a
little confusing. As it already likes to place windows it can't parent
on the opposite monitor to the one with the mouse if there is more space
over there. This is interesting and warrants it's own discussion. What
is the correct behaviour in these circumstances, should we pop it up on
the same monitor as the currently focused window (useful for launching
from terminals) or the same window as the mouse. Some large applications
from ISVs need to span multiple monitors though. So metacity's placement
algorithm already makes sense.
