Obviously, I'm assuming that when you say source control, you're talkin about the listening source at each booth. It would have to be designed in a way that each booth with the backs of each booth going up to ceiling level, with appropriate sound dampeninig, and in an array as to not block the view, it could work. Wireless, not a good idea!! how bout a xantech "waterpad" keypad (totally beerproof).With zpr68 and an 9 zone expansion module you could have 15 separate zones (tables), max volume control, and 6 sources easy. just add 12 channel amp (mono) shouldnt be a problem), and your done!
