Anyone know if there's a remote for controlling iTunes wirelessly? There are various remotes for iPods and so on, but I can't find anything for iTunes. This will be for my friends computer as she plays everything though iTunes. If it's good I'd like to get another one for myself so that I can control Winamp, WMP and PowerDVD, so it's great if the unit is multi-purpose or programmable. Oh, and it needs to be RF and not IR, the control won't always be from the same room. Any suggestions are much appreciated!
