There are some implementation stuff in Python. Some time ago I made 
simple RRD MA and Ping MP and you can find them there:

 
http://monstera.man.poznan.pl/jra1-wiki/index.php/RRD_type_MAService_-_python
 
http://monstera.man.poznan.pl/jra1-wiki/index.php/Python_Measurement_Points

The work on those implementations is stopped so it's not as good as it 
could be. I've got few ideas for improvements but I don't have time now 
to implement them.

Maybe this info somehow help you in your work.
