The ZeroMQ RPC driver was initially developed for Nova and its actor and scheduler driven design. Since moving into Oslo, new projects have begun using the RPC code for different messaging patterns. Some of those patterns are particularly un-actor-like, which poses challenges for the ZeroMQ driver. I've been attacking these challenges head-on and we've made good progress in Grizzly. I would like to discuss what challenges remain, identify new and upcoming challenges for Havana, set expectations, and identify gaps where new blueprints may be necessary.
