One of the best sounding systems in a large open space indoor venue that I experienced was in a beach side restaurant in Aruba that featured Onkyo receivers, Onkyo CD players, and multiple wall mounted JBL speakers.
There are some similarities in that set-up and the barn set-up that you are describing.
Rather than try to wall mount omni speakers, you could go with wall mounting multiple speakers and using an amplifier that supports multiple zones or playing A and B speakers simultaneously.
I have not heard the speakers below, but have read good things about them and more importantly they come with a 30 day home use trial.
Axiom wall speakers
Axiom outdoor speakers
Your buddy could give these a shot and see if they work in his environment.
