We're trying to use an app called Sketch:
http://www.bohemiancoding.com/sketch/
And there's some sort of mirror function that works between the mobile device and the desktop that uses bonjour to find each other, but I can't seem to make AirGroup pass it. They say the service is _BCBonjour._tcp.local but this config didn't work:
airgroupservice "Sketch"
id "_bcbonjour._tcp"
description "SketchMirror"
!
airgroup service "Sketch" enable
