Hi-fi company Naim has released an iPhone control app for its UnitiSystem wireless multi-room audio system, which streams music around a house wirelessly. 

UnitiSystem comprises the UnitiServe hard disk player/server, and NaimUniti and UnitiQute all-in-one audio players, controlled by the app. The UnitiServe is a CD-ripping, hard disk music player. The Naim Uniti houses a CD player, integrated amplifier and multi-format tuner, delivering FM, DAB and internet radio. It also has iPod connectivity. The UnitiQute is similarly specified. But lacks the CD player.

The UnitiServe costs £2,000, the NaimUniti £2,100, the UnitiQute, £1,350, and the iPhone app is a snip at £25.
