So 'other apps', does that mean Orca and other screenreaders, or does that mean 
EVERY application needs to support it for the magnification to be able to 
follow focus?!?

Or can any magnification tool follow focus in any app which supports AT-SPI 
properly? Sorry, I don't really know how all this is chained together....

I think I'm misunderstanding something here...

I'm mostly concerned with getting the magnification (either in Compiz, KWin, 
Gnome-magnifier or KMag) to follow focus - so does that need changes in 
applications or not? Is AT-SPI support enough?
