The Enterprise app developer program is for apps delivered for your own enterprise, not an app in the App Store that is meant to be used by other enterprises. In an Apple Enterprise Developer app, you can basically do whatever you want, but you deploy it to devices yourself, and there is a limit to the number of devices. Apple doesn't even look at these apps. I suspect they reserve the right to police some things (for example VOIP over unlimited data) -- but I don't know that that actually happens.
