Is there a Python interface to the X11 session management protocol library (SMlib)? -

i'm looking python interface x windows session management protocol library (smlib). need have python application linux desktop (not window-manager- or desktop-environment-specific) register part of user's x windows session without tying specific window manager or desktop environment. such thing exist , have name or web site it?

i have documentation cffi write wrapper myself if absolutely have , can find smlib wrappers other languages ruby, i'd prefer use existing package if 1 exists. date searches return results either sms messaging or http sessions web applications/services, nothing related x windows or smlib/icelib.
