Create native extensions (air) for mopub sdk for ios/android

For a project I am managing, I would like to integrate the MoPub ([login to view URL]) sdk into air mobile projects. I would want to reuse this for several projects, so the keys for mopub configuration would need to be configured at runtime, not compile time. For deliverables I would expect the following: 1. one compiled .ANE file and paired actionscript class that will provide easy acces to both banner ads and intersticial ads from the sdk. 2. all source code 3. a demo project in air for functional confirmation
