In 10.1 if you mount the ipod from iTunes, and then in terminal go to
/Volumes/name of your ipod/iPod_Control/
and do an ls you get:
DeviceInfo iTunesDB iTunesPlaylists
iTunesControl iTunesEQPresets iTunesPrefs
so, im not sure what all that stuff is, but it does say EQ...
also you can get to your music the same way, only go to the "Music" directory, the mp3s are split up into subdirs called Fsomething...
Not sure what scheme it uses for the ordering yet.
