Create Auto Crud
Take a project like http://www.mattjcowan.com/funcoding/2013/05/11/restful-api-and-ui-for-typed-views-and-typed-lists/
and lift it to the next level.
Purpose: Point ActiveScaffold with AutoCrud to your database, and you get a half sensible CRUD web interface to maintain it. In other words, an instant backoffice.
This is orthogonal to any other API usage of ServiceStack.
Inspired by the Rails equivalent "https://github.com/activescaffold/active_scaffold" that is very nicely designed, with both configuration and override possibilities.
