We use PyDispatcher + Twisted extensively in Cinemon.  Thing to keep in 
mind is that PyDispatcher is *synchronous*, so if you have a large 
number of handlers/observers registered for a given event you could 
stall Twisted as you process the one event.  We often use a callLater( 
0, send ) pattern to move the event processing into its own "timeslice" 
for heavily-observed events.

Good luck,
Mike
