title: Using Rx with, or alongside, Prism's EventAggregator - suggested approaches?
body: <p>It strikes me that there is both some overlap and conflict between Prism's <code>EventAggregator</code> and Rx Framework, in that both are about subscribing to event streams. Rx obviously provides much more fine grained control, whilst the <code>EventAggregator</code> provides a loosely coupled, application wide, pub-sub infrastructure. </p>
  
  <p>So my question is this, how can we effectively utilise both technologies together in the same application? Am I confusing their roles, or is there a distinction somewhere that I have missed? Does anyone have any experience of doing exactly this?</p>
