Some aspects of software development are 'Apple Developer Confidential' and can only be shared between official Apple developers. So I'm not sure how I would be able to distribute an iOS App or Mac OS X App about developing Apps for iOS and Mac OS X ... I mean iTunes iOS App Store and Mac App Store are ideal places but I don't know how I would enforce a restriction that the App only be used by official Apple Developers. Unless there is some example code somewhere for verifying Apple Developer status. Any ideas?
