Call Me Fishmeal.: "The Mac App Store has been a huge boon to Mac software developers, but has an enormous flaw: it needs to allow developers to charge existing customers a discounted price for major upgrades."

I'm going to agree that some kind of system is necessary. Without new features to the Mac App Store, upgrades are always going to be full-priced with new SKUS or free via an existing SKU. Although I imagine in-app purchase could be used to effectively sell upgraded functionality to an existing customer. Not that the customer would like it, mind you.
