title: Event Based interaction style in REST
body: <p>I am currently struggling with a design issue involving REST. The application I am designing has a requirement to send out events and also support pub/sub style of interaction. I am unable to come up with a design to provide these interaction style without breaking the REST’s “Stateless interaction” constraint. I am not against polling as some people seem to be (polling sucks) , but my application demands a event based and pub/sub style of interaction (polling is not an option for me). So, my question is:</p>
  
  <ol>
  <li>Can I design a RESTful application that supports event based and pub/sub interactions without breaking the REST contraint? </li>
  <li>Is REST style suitable for this kind of interaction style? </li>
  </ol>
