The site looks like it has pretty much everything already, including invisiwire. I would have to conclude that quality video cables for game consoles would be a great addition, currently there is not a lot to choose from for those. I found the component switching devices, but with HDMI becoming more popular it might be time to think about adding a switching device for that. Also, cost permitting, I think more affordable component and HDMI switches would be good in the <$100 range. Chances are if someone doesn't have enough connections, it is probably because they couldn't afford the more expensive equipment options at the time or can't afford a full upgrade on the stereo or tv currently.
