The work is going slowly because the Python C extension API has lots of subtle quirks. The good news is that Google has Python implementation experts who are reviewing the code. But this is "20% work" for everyone involved (i.e. not their real jobs) so it will take awhile.
My hope is that we'll be able to release it in a couple months.
