Why doesn't Vista expose individual pairs of channels as separate endpoints?

One of the questions that was asked after EHO and my Channel 9 video aired was: is there an ability in vista to set on which speaker you hear an application? for example i want the media player on the 2 front speakers and the game on the 2 back speakers? Read More...
