Everything should be in here - 
https://github.com/openshift/enterprise/tree/enterprise-1.0/install-scripts/amazon

I noticed bleanhar has done the last few updates so he's probably the 
leading expert there now too.

Yep, that will probably be the trickiest piece for us.  I'm still 
thinking about the best way to bring multiple machines up that all know 
about each other without fixed DNS addresses but I'm sure there is a 
way.  The main reason we use DNS is so that we can provisioning 
everything in 'parallel' (even though CloudFormations really doesn't) 
and when the machines come online, they already know how to connect to 
the other machines.  For example, when the broker is provisioned 
(broker.example.com), we configure it's connection to mongo by expecting 
the mongo machine to be at mongo.example.com. We'll just have a find a 
different way to do that.

I did all of my testing with the latest RHEL and I essentially added 
cloud-init to it and burned my own AMI.  That was key to how we 
kickstarted the machines.  I believe Origin works on F17 right now but 
we have a known issue with F18.  Krishna - any updates there?

We should eventually start using the coprs repository (3rd party 
repositories built through Koji) but it's not there yet.  In the 
meantime though, we might need to publish a temporary location since the 
yum repositories referenced in those are stale.  Krishna / Bill - any 
ideas here?
