title: Amazon EC2 autoscaling instances with elastic IPs
body: <p>Is there any way to make new instances added to an autoscaling group associate with an elastic IP?  I have a use case where the instances in my autoscale group need to be whitelisted on remote servers, so they need to have predictable IPs.</p>
  
  <p>I realize there are ways to do this programmatically using the API, but I'm wondering if there's any other way.  It seems like CloudFormation may be able to do this.</p>
