Twisted sort of has that with ampoule. The main issue is that arbitrary object serialization is pretty much impossible. Within threads, you sidestep that issue completely; across processes, you have to do deal with serialization, leading to the issues with pickle you've mentioned.

I would prefer something more generic.

So maybe something like is popular in JS, where you subscribe to events by some string identifier? I personally use and like AngularJS' $broadcast, $emit and $on -- quite nice, but depedant on a hierarchical structure that seems to be missing here.
