Oh interesting! Care to share a small write-up about how you set it up?
I couldn't get to CloudFormation template deploy working, so set it all up by hand, using the scripts in that repo as a base.
Once you figure out how it works, it becomes easy to start adding other commends to run (for example, I added some lines to invalidate CloudFront when I uploaded a blog post).
If I get a change over the next week or so I'll update a repo with the scripts I use, but as I said it's based on the above anyway.
