Ok, all this sounds cool, but I'm wondering if all of these remote control units are based infrared or radio waves? The reason for my concern is that my conputer is in the basement while my home stereo system is in my living room, one floor up. Can any of the devices listed in this thread be used with a computer that in on another floor or in another room? Maybe there are some supplemental wireless devices that can be used in conjunction with these remotes?
Thanks,
Mo
