I wouldn't be super quick on drawing the front-end and back-end distinction. A front facing interface using sockets could (depending on how flexible we are with terminology of course) be considered front-end too. And I think that's the entire point of the article.
I have seen huge benefits, performance being one, communicating using ZMQ (at the cost of complexity and reliability). A worker, running on your computer, consuming data fed through a socket from a broker, running on your server.
