Creating a program for broadcast avahi

I am trying to write a program that outputs data that can be transmitted over a network with avahi. The documentation I was looking at seems like I need to register the service with dbus and then connect it to avahi, but the documentation for this is pretty scarce. Does anyone know of good documentation for this? I looked at them:

python-dbus: http://dbus.freedesktop.org/doc/dbus-python/doc/tutorial.html#exporting-objects

python-Avahi: http://www.amk.ca/diary/2007/04/rough_notes_python_and_dbus.html

I'm really not familiar with how avahi works at all, so any pointers would be helpful.
