In part.  I see that libfitbit has come a ways since i looked last year.  Includes a section on reverse engineering now.

There is a new project for newer fitbit devices, called Galileo.

https://bitbucket.org/benallard/galileo

So it looks like there is more to dive into.

These was a proprietary project that claimed to fully decode fitbit protocols, called fitbite.
