I'm not sure on its own that a "more secure" app marketplace is filling any specific need. I think rather you'd want to think about being the provider for various organizations that need secure marketplaces of their own. For example, various countries/organizations may want a set of applications that meet specified criteria. You could still have a single marketplace internally, but to each customer, it would seem that you have a customer-specific secure marketplaces. But first, you need to have a customer to provide this service to. And find out your competitors. For example, I believe at least one U.S. military branch provides their own apps. Could you provide something they can't do on their own?
