@3DPiper: Or could you use DLNA/media sharing to achieve this?
ie. have two networked machines. One would be connected to the projector, the other would be "connected" to the user. The user can then access media files on the projector box, create a playlist, tell it to play etc. via their machine. Presumably you would have the content stored on the machine connected to the projector, unless you have a good network.
IIRC newer versions of Windows Media Player may be able to do this, I can't recall off the top of my head, though, whether you can use them to control playback from another computer or merely playback files from other servers (and serve files to other computers to play back). I won't be in a position to check this for the next few days either.
EDIT: You should be able to achieve this:
