on 1/2/2010 just left a house that had two into one, but the fan motor was the standard bathlight/fan combo in each bathroom and the roof exit hood has a flap damper to prevent infiltration backflow.. Cold air from coming back in. What happened when one fan was on the air would go to the other bathroom ... the path of least resistance hahah fart transfer eww. but seriously great solution.
