title: Dynamically creating live RTMP stream on AWS?
body: <p>I've read a bunch of tutorials that let you create a live stream with CloudFormation, but I'd like to run a website in the style of UStream or Justin.tv that lets someone go live in a completely automated way.</p>
  
  <p>To do that, I'd like to be able to run backend code that creates a new live stream on-the-fly and returns the RTMP url to publish/listen to.  Obviously I'm not deploying a whole cloudformation stack here, the EC2 instance with FMS would already be running, but I just need a new publish and play url, if that makes sense.</p>
