	Actually, I don't know for sure how it's implemented.  They may 
have separate sound streams for each window.  Moreover, this was a 
few years ago (I left in 1995), and there may have been changes since 
then.  It would certainly be a lot easier to use individual speakers 
fed by electrical wiring, than pumping a lot of air around from a 
central location.
