Thank you for this very interesting thread on Apple TVs. We are also trying to deploy some apple TVs and are having issues. Faculty are trying to use ipads and air play to connect to apple TV, which is in turn connected to an HDMI converter which is in turn connected to a VGA projector. Our projectors are connected to our hidden wireless vlan - which is wpa2-psk We have gotten the apple TV on the same SSID and vlan as the projectors and it is getting a good ip address from DHCP. We have the ipad on the same SSID and vlan as the projectors and apple TV and it is also getting a good ip address from DHCP However, airplay does not work, the ipad cannot see the apple TV We are all cisco (AP, WLC,Firewall,etc). There is a new software update for Apple TVs called the APPLE TV CONFIGURATION PROFILE which was just released last week that is supposed to allow for connection to enterprise networks http://support.apple.com/kb/HT5437 We set up this up today, but still no luck, airplay on the ipad is not seeing the apple TV. Has anyone else encountered this? Am I missing a step in the process?

My guess would be that you are having issues with Multicast (bonjour) packets. Here is a Cisco guide to using it in their environment:

Carolyn: That is SO HELPFUL! Thank you! I had not yet read that AppleTVs now support 802.1x—we're going to try it next week!

I wanted to throw in my two cents.  (Yes, I know I am late to the party here).  I'll preface this by saying I haven't had a lot of experience with Apple devices having to support only a handful.
 
If you haven't looked at it closely, I feel compelled to re-enforce Mike's suggestion about this Cisco guide even if you don't have a Cisco wireless LAN controller.  There is a lot of information in this document about what needs to be in place for an Apple TV to be seen on a network, isolating the Bonjour traffic to its own VLAN to keep network traffic down, but also a method that allows those Apple devices to been seen across VLAN's via a Bonjour Gateway.  There are even special recommendations for wired Apple TV's to make them work better.  I haven't really sorted through all of it (and probably will not do all of it because we only have one Apple TV at the moment) but I thought it touched on a lot of topics that came up in this thread and in a previous one where folks were concerned about the traffic created by Bonjour.  I felt it had a good explanation of how Bonjour works, and what you might have to do to manage it.
