Wireless audio switch with Apple control capabilities?

[Jagshund]

I have an Onkyo NR609 in the theater with 2 zone capability and want to use it to drive three without getting too complicated. The theater is Zone 1 and Zone 2 is currently the gym; rarely do I ever find my wife in the gym while I am in the garage so, getting tired of tinny music, I was thinking about running another set of speakers to the garage and switching between the gym or garage with my phone or ipad (most everything in the house can already be controlled in this manner). Blasting both the garage and gym at the same time would not be an optimal situation even though the receiver could probably handle it.

Does anyone know of a wireless audio switch (splitter of some sort?) of this type without having to delve into Control4 devices? Or another solution ~$50-100?

If your music is iTunes/etc. driven you could consider getting a few Airport Express devices and you can individually select each device and it's volume from your phone/ipad. $89 each. You would need a seperate power amp or receiver for each 'zone' though.

I have 3 computers on my wifi and 2 airport express(es), for a total of 5 "zones" that I can control via my phone from anywhere in the house. It's like Sonos on the cheap, sort of.
