I was going back and cleaning up some of my projects I've worked on. I factored out an event broker component that was extended from the broadcast pipe: simpy-event-broker. If interested, I could clean it up a bit more. Not sure if you are looking for application examples, or possibly some re-usable components. If the latter, would you rather see them integrated into simpy or built out as a separate python module and hosted on pypi?
I like to see external python packages first. We can link to external packages in our documentation. After a module has proven itself in real world usage for a while, we can talk about integration into simpy.
this looks indeed nice, but I agree with Ontje that it would be a better idea to release it independently of simpy. We would then add a list of SimPy extensions to our documentation and point to your project.
