looks like it would have a pretty limited application. I mean, it wouldn't be able to do anything more than a normal universal remote could do anyway right? It certainly wouldn't be able to cooperate with VC because I imagine that it does simple command recognition on a chip and then just sends infrared like a normal remote would.
I doubt the command structure would be very sophisticated either. It's not like you could ask for a particular band or movie etc...
I didn't look too carefully so I could be wrong... but I doubt it.
There is another remote on the market though that actually works as a microphone. I believe it comes with a software designed specifically for controlling WMC. It looks pretty good, but I don't think it would work with anything else, is not very customizable, and is a bit expensive. Still the actual hardware might be usable with VC if it just shows up in windows as a sound recording device. It also has the neat feature of being able to tip it up (microphone on) or tip it down (microphone off).
