I mentioned the Kupuk Zones a while back; an application for the Apple iPhone / iPod Touch that lets you control the Sonos Zone Players. Now Sonos themselves have released a zone controller for the iPhone. The reactions in the community the last couple of days have been hurrayingly positive and admittedly the logic of having Sonos themselves do the development would by itself be enough to warrant such a reaction. Now they only need to release a Zone Player application for PC and Mac to keep their shareholders a tad on the fringe.
