In order to stream the audio of an output device, you will first need to tap into the output device stream to get the audio data.
Unfortunately this can’t be done easily, but has been achieved by others.
A program called "WireTap Studio” does this using a kernel extension and helper daemon.
More specifically, the kernel extension (kext) uses IOAudioEngine.
Basically, this won’t be an easy task.
Maybe someone else on the CoreAudio-API mailing list can help.
