Can I use core-audio to play back iTunes DRM'ed music?
No, for exactly the reason you described: it would allow conversion to
non-DRM'd formats. The only way to play back .m4p files is to use
QuickTime's high-level Movie API (or the equivalent QTMovie class.)
This gives you basic transport controls but no access to the
underlying samples.
(Also note that there's an entertaining DRM-related feature in
QuickTime: if it's loaded a protected audio file, and detects that a
debugger is attached, it will abort the process. I've had this happen
to me a few times by accident!)
