I came across this today:
http://createdigitalmusic.com/2007/06/06/liveapiorg-new-open-source-unofficial-sdk-in-python-lets-you-hack-ableton-live/

Anyone have any experience with it ?
Since I heard about Max for Live I wondered if it would be possible to
have a Python for Live module, but it seems it's already been there
for some time. Now, to figure out how to interface the
Csound-Python-Live connection might open up some possibilites.
