Yeah. I suppose the idea of a "virtual empeg" (vs. backup) would be so that one could go ahead and keep updating playlists, tags/dbinfo and tunes, etc. while the empeg was not available (in car/in repair) which could later just be dragged back onto the unit when it became available again.

Perhaps a bit obsessive here?
