Thank Apple for not liking Adobe... despite the fact that most people own macs to run Adobe software... go figure. I think Apple just doesn't like not owning Adobe.
Because no iDevices have flash, you can't stream with flash. The only stream method left is HTTP Resume. You need to install the AV Module, and go into it's advanced settings and remove the tickbox next to disable http resume.
This will make your network more vulnerable as the AV module can't scan partial files. However, it's the only way to get streaming on iDevices. The best solution would be a rack for the iDevices, and use reservations backed with policies to move those devices into the other rack.
