But this is starting to change. One capability that has somewhat filtered through recently has been multi-room audio, which had to go wireless with the Sonos music system. While a Sonos system is still a relatively expensive product, but it is a drop in the bucket when compared with systems such as those from Russound. And telepresence may be getting next in line. The recent release of the Avaak Vue lives up to its promise of being a relatively simple and affordable product that extends webcams to walls, allowing consumers to peek in at will at what is going on at their home. Access is from a simple Web site that allows you to view up to 50 cameras around the home by dragging and dropping them onto a Web page.
