Jay, The original requester was asking about auto-populating the roles based on using the ec2 described instances.
Which is valid, I've written similar auto role populating scripts for scalr. It's great to not have to keep updating the roles list manually for an auto scaling farm when the information you need is only an API call away. I didn't find anything relevant on your site that addresses the same problem for newguy. Also I was less worried about WHAT they were trying to do, but how to better express HOW to do it in ruby and capistrano.
