Not that that has much to do with anything.  There's many other
contributors from various sources, including companies and individuals.

To answer the original question...

You can use libnm-glib, or you can use D-Bus directly.  The wiki pages
above have information on the D-Bus API which is very easily used from
Python or other languages with D-Bus bindings:

http://projects.gnome.org/NetworkManager/developers/spec-08.html

Basically, you can send new configuration data to the system settings
service, which will save your modifications to disk-backed
configuration.  Let us know if you more specific questions about how to
do this.
