It seems unlikely that this would ever be possible. If it were, it would open a huge copyright hole. For instance, you could buy a movie on iTunes, then have your app 'record' it while it's playing in Movie Player and then send the movie elsewhere. This will almost certainly not be possible using the released SDK API, and the task would likely be quite non-trivial even in a jailbroken content. Even if you figured something out, I can't see any way that an app with this functionality would be seen as being in compliance with the App Store guidelines. (Sections 8.5, 9.1, and 22.4 all look relevant here.)
