title: Blockly Example of Multiple Workspaces
body: <p>I'm attempting to create a platform that allows students to play code challenges head-to-head using blockly. I'm imagining something like:</p>

  <p>The documentation mentions "Multiple workspaces" with <a href="https://groups.google.com/forum/#!topic/blockly/EoCr5pbwKIY" rel="nofollow noreferrer">block factory</a>, but I feel like I might be reinventing the wheel here, so before I get started, does something like this already exist? Ideally, hooked up to app engine so students could grab code from any other student and test to see how their code compares?</p>
