With all of the transfers being done via ftp, does that mean that the player would continue to play it's software until the database rebuild kicks in?

Ummm, I think it would be possible to delay the sync until the DB needs to be rebuilt but I wasn't planning on making that drastic of changes to jEmplode. I don't want to break any of the existing stuff so I am only modifying the routines for uploading songs and deleting songs. Maybe later I will think about it....
