If the player was able to manage the database like emplode you could have a 'for sync' directory on the drive, then plug the drive into your PC (in linux) and copy mp3's straight to the drive at high speed, next time you start player it see's mp3's in the 'for sync' directory and moves them to where it wants them and updates the database. This would remove the necessity of fast ethernet (Of course you have to remove the drive - but hey, you've already removed the empeg from your car).
