Kenan is working on this: Decryption and Encryption works, unpacking down to fsimg level, repacking up from level3.

Form of extraction must allow later to put it all back in firmware in identical form, preserving all elements (users, rights, etc)

Planned ARM disassebler we will be using - http://www.hopperapp.com/

I am in touch with author, so if you have questions or license request (after providing proof of your skill), contact me.

jwise has an ARM IDA/Hex-Rays license and can help RE things on demand, but does not have time to take a lead role right now.

Testu is working on the reversing of av-cam.bin with IDA 6.1, but can't promise much time either. The primary goal is to learn the NEX E-mount lens protocol, and NEX 3rd app/extension development.

The app/extension support of the NEX 5R and NEX 6 is done via a custom Android build running in the background. If we can successfully alter the android system and flash it back to the camera, custom 3rd party apps are a very real possibility.
