We couldn't wait until the guys at Google released their reference server implementation, so we decided to build our own in the meantime.
This implementation uses Django - a well-known python web framework - as its backend and is in a very early stage. Just as Google, I want to release it to the public as fast as possible.
In the end, this will eventually be a full-featured server implementation for easy use, extention and integration with your web servers and applications.
Note: All of the code is directly derived from Google's published Wave API and protocol specification.
