title: What Notable Differences are there between Railo, Open Bluedragon, and Adobe Coldfusion?
body: <p>An attempt to capture <strong><em>notable</em></strong> differences between implementations:</p>

  <li><a href="http://www.adobe.com/products/coldfusion/" rel="nofollow noreferrer">Adobe ColdFusion</a></li>
  <li><a href="http://www.getrailo.com/" rel="nofollow noreferrer">Railo</a></li>

  </ol>
  
  <p>(I'm aware of <a href="http://www.smithproject.org/" rel="nofollow noreferrer">Smith</a>, but don't believe it's still active). </p>
  
  <p>Include CFML <strong><em>and</em></strong> platform differences - syntax, feature, and extensibility. </p>
  
  <p>Note, this is not something I've not seen anywhere else, but maybe I'm just not searching correctly. So links to that end would count too. </p>
  
  <p><strong>Update</strong></p>
  
  <p>Here's my definition of <strong>notable</strong> in this context: something that simplifies solving a difficult problem. For example, Railo offers the <code>&lt;cfvideo&gt;</code> tag, which transcodes video - a non trivial task. </p>
  
  <p>Something I would suggest is <em>not notable</em>: the Railo function <a href="http://wiki.getrailo.org/wiki/3-1-Functions:ListAvg" rel="nofollow noreferrer">ListAvg</a>(). </p>
