I have a MacBook Pro running OSX 10.8 and am trying to find out if anyone out there has tested Proclaim with an Apple TV as the second output source? I want to use Apple TVs on my network as my output screens, which can be done with a few other presentation programs for churches. Some of the other programs I've seen provide the ability to send different output scenes to each Apple TV or the same output to all sources. I'm not necessarily looking for something quite that potent yet. *Hint hint! Wink wink! to the Devs! AIRPLAY OUTPUT PLEASE!
