I just found out that there is a very impressive facebook api implementation for python out there : https://github.com/sciyoshi/pyfacebook
Its got 455 watchers :)
And apparently it is very easy to extend as shown here : http://arstechnica.com/open-source/news/2009/04/how-to-using-the-new-facebook-stream-api-in-a-desktop-app.ars
PyFacebook is also very easy to extend when new Facebook API methods are introduced. Each Facebook API method is described in the PyFacebook library using a simple data structure that specifies the method's name and parameter types. PyFacebook does not appear to have been updated to work with the new stream API methods yet, but it was trivially easy for me to do it myself. You can see my simple PyFacebook modifications here.
