Hi, We are currently building an on-/offline application with a shared codebase. In (very) short: what you need to do is start 3 (!) projects in Flex Builder: one Flex, one AIR and one library. The library wil contain most of your code (all of the code that can be shared by both platforms), while the two others contain only the code specific to either platform. All code that is NOT shared between the two versions should be accessed via a Factory method (Google: Design Patterns Factory) which returns an instance of the platform specific object containing that code (both on- and offline specific objects should implement the same interface in order to make them "compatible").
I'm sorry I don't have time for an example, I hope this gives you some pointers to get started.
