Apple has zero corporate presence because as far as I can tell, they don't really try. We tried setting up some Apple TVs at my work to use as an AirPlay target during presentations. But Bonjour can't cross subnets (or something similar), so we couldn't do it. And Apple were absolutely uninterested in providing support.

With the latest firmware + ios7, Airplay now works in such environments because it uses bluetooth for handshaking. Might be worth re-trying?
