Yes, I would like to stream using WiFi connectivity (wireless) in the house. Apple TV looks to be a good solution. Is there another option for connecting a laptop to the receiver and perhaps running some type of software on the laptop and a smartphone?
I just found a device - Belkin Bluetooth Music Receiver - which may provide the functionality I'm looking for.
Using bluetooth is a bad idea it will result in less audio quality. Go with the AppleTV for $99 bucks connect if you want to go wild check out music match for $25 and control it using the remote app from your iOS devices. If you upgrade your OS to mountain lion you also don't need to buy something like airfoil (still has some value) because sending audio/video from the OS is now default if machine is new(er). Other options are things like airparrot and indeed the airfoil set of tools all support lossless audio something that bluetooth won't do and you get video for free.
I did setup the Belkin Bluetooth Music receiver last night and although it provided the basic functionality I'm looking for, I wasn't impressed. I could not step more than 30 feet away from the receiver as the connection would go weak and the quality of the sound was just average. I will definitely go with Apple TV. WiFi connectivity and the sound quality of atv will be far better.
