Syncing is wireless and fully controlled from the tablet, you do not need to have access to your iTunes at all. Just sit in a car near a house and choose a music you would like to hear this trip.
The unique feature is updating the track rating back to iTunes.
To get the tracks on the device mark them and click "Get Tracks" menu item.
Enjoy the music and videos downloaded to /Music/iLcatraz/tracks with your favorite player.
M3U playlist are created in /Musci/iLcatraz/playlist.
To use this app you must install iLcatraz utility on the same computer the iTunes server is running on. iLcatraz may be downloaded from here http://ilcatrazl.s4y.solutions/
On the first launch only playlists and folders are synced. Mark some of them to get a list of tracks you may want to download on your device someday. Do not make too many playlists because it would cause too long synching time.
IMPORTANT: Don't install this app if you have no Mac running iTunes. iLcatraz server does not support Windows/Linux.
