There was this tool I wrote 2 years ago called empegmirror which copied mp3's off the empeg to a local disk.

it's for the v1 software, but it works with USB. I'm reasonably sure that it will work over 2.0 as well.

So, if you can figure out how to store files on the empeg as fids, you can hack this code to pull them off too.
