See how you can control
this thing from your laptop?
I wish someone would make some kind of software for controlling XBMC from my laptop, because I often find myself on the couch, and I have to turn on the TV and pick up the Xbox controller to change the track.
However, I realise that any kind of "remote control" app built for XBMC would be for Windows. I'm a Mac user, so I suggest a universal VNC server that any computer can connect to as long as it's in spec with the VNC protocol.
