title: Piping stream to a variable!? or ....?
body: <p>What are my options to pipe stream to a variable? Based on this <a href="http://nodejs.org/api/stream.html#stream_class_stream_writable" rel="nofollow">documentation</a> the examples of writable stream include:</p>
  
  <ul>
  <li>http requests, on the client </li>
  <li>http responses, on the server fs write</li>
  <li>streams zlib streams</li>
  <li>crypto streams</li>
  <li>tcp sockets</li>
  <li>child process stdin</li>
  <li>process.stdout, process.stderr</li>
  </ul>
  
  <p>So does it mean I cannot pipe stream to a variable to process it? In fact I dont want to save the stream on my disk, so what is the best way to pipe all of the streams and use that data?</p>
  
  <p>Thanks please let me know if you need more clarification!</p>
