I cheat, we use vent for FSO and I also use it for WoT.
I hooked up a second small monitor off to the right side of my primary.
Skype and Vent live over there, so even if we are flying I can see who entered/left channel, who's transmitting, etc.
Vent Overlay also works well, the only problem is that screen resolution needs to be the same for windows and AH.
