No problem, thanks for the script url - I'll start working on my AMI. I first heard about elasticfox from you and it is pretty excellent. Hard to believe it's a browser extension and not a standalone app.

I also applied for a research grant, which I just received, so I'm planning to start moving ahead with use. I have a question that is perhaps less starcluster-related: how do I modify the existing AMI and save it? And then how would I make star cluster launch that instance going forward?
