DBus-Python - Getting Started

[David Collins]

DBus,

I am trying to get started with DBus python, but am struggling to find
simple up-to-date examples of working Python code.  I am using Python 2.5.1
(r251:54863, May  2 2007, 16:56:35) and dbus 1.0.2-1ubuntu4 on the current
version of Ubuntu (7.04 Feisty).

Can anyone point me to a good learning resource for using Dbus in Python ?

I think that using D-bus within Python will be a really nice system once I
understand the basics.

The working code below shows about how far I have got, so far. :)
