[python] How can a noob get a simple implementation?

[Sean Meiners]

Based on my experience with the python bindings (which is quite a bit  
lately) you should be able to achieve 'A' without much fuss.  As for  
how to do it, I just happened to be poking around the python examples  
included in the DBus source tree today (python/examples) and found  
example-signal-emitter.py and example-signal-recipient.py to be quite  
excellent in this regard (thanks again John P).  To try them out make  
sure you have a session bus running and start the emitter first (the  
receiver relies on it).
