Ask HN: Is a security focused Android App Market a good idea?

One of the major concerns for one of my iPhone friends who I am trying to convert to Android is the security that comes from the more open platform, and I explained the current security level.

So I began considering the idea of an App market that is heavily security focused. Each app is auto-reviewed by a system which looks for obvious threats to security. Then there would also be paid app-reviewers who go into the code and trace, explore, etc.

App inclusion in the market would be based off submissions by app authors, it would include a questionnaire (like the apple market), as well as an application fee (once per application, no matter number of rejections) etc. This is a clearly defined system, the apps permitted in this market are only "apps" and not "games" and no wallpapers, etc.

Customers would be able to subscribe to it and have access to the reviews, as well as subscribe to reviews by various reviewers.

So - what do you guys think? Is this feasible? Is there a business in this idea?
