	Of course, as Chris Lahey pointed out just the other day, one of the
main points of this feature is to make sure the user REALLY IS typing
their password into the application they think they are tying it into. 
Another window can't just pop up, grab focus, and display what they are
typing.

	And, as another side point, I had a sawfish and panel crash the other
day when using GNOME 2.  All I could (easily) do was ask Nautilus to
open a terminal which I couldn't type into since I couldn't ask it to
grab the keyboard.
