title: Zeromq which socket should bind on PubSub pattern
body: <p>I have been reading about ZeroMQ more specifically about NetMQ and almost every Pub/Sub examples I saw used to Bind the Publisher socket and then the Subscriber socket connects to the other.</p>
  
  <p>So i'm wondering if it is possible to do the reverse, i mean Bind the Subscriber socket and then publishers connect to it.</p>
  
  <p>Is this possible ? (I didn't found anything clear on documentation)
  What are the disadvantages using this connection strategy ?</p>
  
  <p>Any help will be usefull.</p>
