Short answer: No.
Long answer: Since JLJ has left, someone else would need to reverse engineer 
the DRM format, and extract the keying data from the correct place.

Short answer: None.
Long answer: You need some keying material from the iTunes installation and 
hardware identifiers, and obviously to have bought DRM'd files through iTunes 
a long time ago. As far as I know, this code always required some manual 
configuration, so it was never widely used.

Short answer: You cannot.
Long answer: See above.
