I've got a feeling that NetworkManager's dbus interface doesn't have an
API guarantee at the moment.

I just chatted to one of the lead coders on NetworkManager (Chris
Aillon) and he thinks it makes more sense for applications to use the
GLib bindings to NetworkManager, rather than the underlying DBus
calls.  

Here's the GLib NM API:

http://cvs.gnome.org/viewcvs/NetworkManager/gnome/libnm_glib/libnm_glib.h?view=markup

And here's an example of using that API to monitor changes in networking state:

http://cvs.gnome.org/viewcvs/NetworkManager/test/libnm_glib_test.c?view=markup


Hope this helps
