Would you say that open-standard systems like the Media Center PC represent a serious challenge to the current proprietary control systems?
There is a marriage. Media Center PCs are good for some things and not for others. Usually, a general-purpose machine isn't particularly excellent at anything. I've got a Media Center PC and, quite frankly, it's not reliable enough to use as my distributed audio system. So I still see for some time to come purpose-built distributed audio/video systems that are semi-proprietary. Our system is semi-proprietary in that it's our system, our programming, and our wizard that sets it up, but it interfaces with XM and Sirius and HD Radio, which are open standards, and it uses the Ethernet protocol to distribute the metadata and control signals around the house, which is, again, an open standard. But it doesn't have a Microsoft Windows operating system that will let you do a spreadsheet and everything else on it. And because it's not, it can be made purpose-built and extremely simple and dedicated to what it does.

Where the interface will come in is when these proprietary systems will be able to talk to and through a computer or be controlled by a computer, should you want to. So I could sit at my desk with my computer and I could download music from iTunes, and my whole-house system could then access that data that's stored on my computer's hard drive as if it were another source — as if it were a radio or CD player or cable box — and control it as if it were a source. Vice versa, I could put an interface on my computer that would enable me to control my whole-house system as if my computer were a keypad. So I see a blending of proprietary and open standards. I don't see a Media Center PC or Vista operating system taking over the whole-house market.
