Default Remote controlling WMP

Hello

I currently connect my Hermes to my Pioneer in-car head unit via 2 cables, these are a usb to RCA (phono) and then RCA to iBus (iBus is the Pioneer interface for connecting and controlling external multi-disk cd stacks).

Obviously the signal is sound only with no controls.

My question is that in the states Pioneer seem to be releasing players with a new interface, the uBus, this lets the user controll various MP3 players:

do you think that this will control Windows Media Player on a Hermes? My guess is no, but if someone with more idea about the workings of WMP could take a look and let me know there thoughts, it'd be much appreciated.

If not, then purely out of interest, is there any other way people have controlled WMP remotely, via some hacked headphone and a WMP plugin maybe?
