I have the audio from my laptop running into my home theater receiver and then out via an FM transmitter, which I tune to on my garage stereo in order to listen to music in my backyard.  I would like to have a remote that I can use from outside my house to change songs (forward or backwards).  I would prefer something that is compatible with multiple programs (not just Itunes, since I currently use Yahoo Music Engine).  Can anyone suggest a device that would accomplish this for me by USB, Bluetooth, or anything else?  My laptop doesn't have bluetooth capability, but I could always buy a PCMIA card if I need to.
