python-daap
Finally I have a set of python classes that will talk to an iTunes shared library and let you look at the track list, playlists, etc, and download songs from it. They're based on Davyd Madeley's code as a base, and I've drawn heavily on Net::DAAP::Client and the daap wiki for reference. I don't have a formal release tarball yet, but you can get the code from my svn repository for now. You'll need python-md5daap installed to use it, as well.
