New iPhone Dev policy...how does Apple enforce this?
<p>Apple doesn't want anyone to create iPhone apps outside of the Xcode/Objective-C environment.  How can they actually enforce this?</p>

<p>If the non Xcode IDE, for example Unity, compiles to an iPhone executable, how will Apple know which dev environment you used to create the app?  Can they have Xcode compile some sort of signature into the executable that no one knows about?</p>
