Yes, this is commonly called a message bus.

ZeroMQ supports this, you can just use a forwarding device where on one end you can connect the publishers and on the other end the subscribers.




Thanks Nicholas - I'd heard that term before but not known was it was till now. How do people avoid the forwarding device becoming an SPOF?


From the article: ZeroMQ follows a brokerless design so that there is no single point of failure.


There's no SPOF unless you create one. So the sentence should be more correct this way "ZeroMQ follows a brokerless design so that doesn't enforce single point of failure."
