1. Will there be any way to give volume license discounts? 2. Will there be any way to set up payment through the AppStore for a subscription model (GPS navigation software might use this, for example, where you get updated maps). 3. How does the updating work? You just upload a new version and each current user gets a notification on their iPhone. With the new push notification service this should be possible. 4. Is there an Apple approval process (delay) for each update, or can I just upload and it's available? 5. How easy is it to change the price of an app? Will I be able to upload beta versions for free to have people test them, and then start charging at full release? Or must I use the Ad Hoc model for beta testing, with its limitation of only 100 users? 6. Is there a facility for demo mode where the user downloads the full version and gets an unlocking code when they decide to pay? Or would you just post a separate crippled demo version? 7. Will there be links to other products by the same developer? What about links for "other users also downloaded..." like on the iTunes store and Amazon? Ratings and user reviews? 8. Why not an AppStore for desktop Mac apps as well?
