Setting up two wireless headphones/mics, itunes in real time on a Mac

Folks,

I’m very new to this so please excuse my question if it has a really simple answer.

I want to connect two wireless headphone/mics together so everyone can talk/hear in real time. I also want to be playing an mp3(one or more) that everyone hears.

Can I do this with Ardour? or even without on my Mac running Snow Leopard.

Thanks, Walt
