I was looking for something like this to control a Wirelessly networked remote PowerBook which is hooked up to my Stereo System from my office Desktop which is were all the actual music resides(Share the Playlists with the Remote through iTunes). Just setting this up seemed sort of cumbersome and I could not even get through the set up without the silly pop ups preventing me from trying the thing out as they occur every few seconds. With a little research I stubled upon NetTunes which was way easier to set up, Works perfectly and gave a decent 30 minute trial to really check out how it functions in my environment. Check it out, I think it's much better and Easier to set up.
