title: a-frame networked - how to match an avatar with a broadcasting client?
body: <p>I'm using <a href="https://github.com/networked-aframe/networked-aframe" rel="nofollow noreferrer">aframe-networked</a>, and I'm sending some custom data between the users:</p>
  <pre><code>// sender
  NAF.connection.broadcastDataGuaranteed(dataType, data)
  // all recipients listen
  NAF.connection.subscribeToDataChannel(dataType, (senderId, type, data, target) =&gt; {})
  </code></pre>
  <p>but I'm having trouble determining which avatar entity is corresponding to the broadcasting client. How the receivers know which player is the <code>sender</code> from the callback?</p>
