- Support for a virtual empeg (or riocentral) device
This would allow you to essentially back up (via click/drag) all of your music/playlists/dynamic partition stuff locally, organized as on the player, to allow for complete restores after catastrophic events.
Obviously, it would be a virtual device only in the sense of keeping track of the data and would not operate as a player.

I suspect it'd just be a folder hierarchy controlled by jemplode with data situated accordingly.
Useful for people with no backup unit.
Not sure this is a top request, but more something that came to mind the other day and I couldn't dislodge it for some reason. It may be a monumentally bad idea.
