Yeah, just to add to what Timothy has said --

One reason I chose twisted was because ideally, I wanted to send *objects*
back and forth, not strings.  With Perspective Broker, you can get pretty
close to that ideal.

And like was said before, you don't have to let Twisted control
everything, you can use reactor.iterate().

I've written about my findings here:

Any comments / criticism would be more than welcome.
