title: Is there a way to reverse the bind on zmq pub/sub?
body: <p>I have server code on one box that needs to listen in on status coming from another box with about 10 chips with linux embedded in them.  The 10 chips have their own ip addresses and each will send basically health status to the server which could (possibly) do something with it.</p>
  
  <p>I would like the server just to passively listen and not have to send a response.  So, this looks like a job for zmq's pub/sub.  Where, each of the 10 chips have their own publication and the server would subscribe to each.</p>
  
  <p>However, the server would need to know the well known address that each chip bound their publication to.  But, in the field, these chips can be swapped or replace with a different ip address.  </p>
  
  <p>Instead, it's safer to have the chips know the server code's ip adddress.</p>
  
  <p>What I would like a pub/sub where the receiver is the well known address.  Or, a request/response pattern where the clients (the chips) send a messages to the server (the requests), but neither the server nor the chips need to send/receive a response.</p>
  
  <p>Now, currently, there are two servers on the separate box.  So, if possible I'd like a solution for one server and multiple servers.</p>
  
  <p>Is this possible in zmq?  And what pattern would that be?</p>
  
  <p>thanks.</p>
