ZeroMQ for basic signalling?

Maybe I missed this in the docs, but how do you use ZeroMQ for simple signaling between multiple nodes? Something like REQ to REQ, with no REPs.

Example: I sometimes want to tell all other nodes to invalidate cache pages or notify them that something happened.

Request-reply won't work because I don't want the requester to block waiting for an empty response. I want to allow multiple signals to build up at the server.

Publish-subscribe feels wrong because I'd have to subscribe to everything, and start two sockets, one for each direction of communication.

PAIRs don't support automatically reconnecting and have other limitations.

Is pub-sub the best way to go? Or am I better just to use a traditional socket, write to both ends, and handle disconnections/reconnecting?

What you want is a dealer socket in your client side and a dealer socket on your server side. If you want to be able to send message to a specific node from the server side, then you better use a router socket in the server.
