Hi ho!

Would you recommend or discourage using pyDispatcher in a twisted application? Are there any known traps?

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
