Revisiting this: I have a Scosche bluetooth audio pair, a receiver which is now hooked to the Aux In on the empeg, and a sender which is just a headphone jack with a battery unit... I actually don't use the sender much now, because Treo 700p+Softick Audio Gateway+Kinoma Player 4.2 = stream WMA via bluetooth, but, I may get back to this; It would mean no need for a remote display (which I can't afford now, anyway) assuming AVRCP could be coopted for enough track selection functionality.
