This looks great! I tinkered with building a similar service-oriented bot, using ZeroMQ for communication (though not very robust as it would block for responses IIRC); http://demonastery.org/2012/07/building-a-decoupled-irc-bot-...

Have you looked at ZeroMQ pub-sub yet? It has a flag for non-blocking publish.

Also thanks!

Thanks for the heads-up! Would be a fun project to revisit
