I was thinking of letting them call "send" but it seems that that is not thread-safe. From the guide, it appears I can use inproc+xpub socket from producers to a proxy and let subscribers connect over TCP/xsub. However, there is no example code. 

I answered your question on irc. When asking a question, you should stick around for more than 5m to get an answer.

Create a forwarder device that all of your PUB sockets connect to. All SUB sockets should then subscribe to that forwarder. You do *not* need to mess with XPUB and XSUB sockets.
