iTunes module code

I was just wondering if the code is available for the iTunes Plugin
for Quicksilver.

I'm running into what seems to be a fairly common problem that the
iTunes Plugin notifications don't show album artwork for some of my
tracks.  I've updated all of my ID3 tags to V2.4 but it still won't
show art for all of my tracks that it should.  I was just wondering if
the code was floating around somewhere so I could toy around with it
for a while to see if I could get it working with my machine.

thanks, John
