Hi Dan,
     Yeah, I have been playing with them a little bit which is what
brought up the idea. The plugins are exactly as you said a post startup
hook. If I had a pre-shutdown hook I could save state about the cluster
prior to shutting it down. I guess there may not be that many actions
that need hooking, but I just thought I would throw the idea out there
so people could give it a think.

     For the most part, I am doing slightly goofy things with
StarCluster and I don't want to annoy you guys (and Justin) too much.
But when I think of something that is generally useful I thought I would
share. Like the _setup_sge() thing. I know thats the /main point/ of
StarCluster, but its also the only line in DefaultClusterSetup that
makes StarCluster a SGE Cluster creator for EC2 rather than a generic
cluster creator for EC2.
