One of my first thoughts. The purchase of a license would need to occur on the web-based store, where presumably you'd create an account, download the free (with in app purchases, because you don't want to restrict sales even if they're at a lower margin) app from the App store, and sign in with your account to activate. Seems like entities wishing to operate a secondary app marketplace would continually be balancing tradeoffs in UI/UX (v. native Apple experience) and cost of acquisition for a relatively small reduction in fees.
