There should be a mobile optimized website, where you can download and import profiles, tasks, projects and AppFactory-apk's.
Something similar to this,but not for ebooks (
Demo website):

Every contribution needs an icon, a short description, tags, required plugins, etc.
A seperate Tasker plugin could make it possible to setup an account for the database and exporting the content directly to it.
Contributions could be marked as public, private, private beta and so on.
