Hi Marko,

You're right about the other instance with a different keypair being the issue
and it's related to the fact that the current version of StarCluster does not
support multiple clusters.

This is fixed in the latest development code on github. I'm in the process of
cleaning up the current code in github and putting together documentation for
a new release that supports multiple clusters, multiple ebs volumes, cluster
'plugins' that allow users to write their own custom setup routines on top of
starcluster's defaults, automated ebs volume creation (including
partition/format), and more.

Stay tuned...

~Justin
