[StarCluster] Customizing AMI but to distribute share

[greg]

Hi there,

So I'd like to install some custom software on StarCluster and then
allow others to run their own instances of StarCluster using my
software.

This page seems like a really good start:

http://star.mit.edu/cluster/docs/0.93.3/manual/create_new_ami.html

But I'm not sure how I would share the EBS AMI I create so others
could launch StarCluster with their own AWS accounts, and instantly
run my installed software.  (Also I guess ideally it would be good if
they couldn't modify the original AMI, but could persist their data
somewhere else.)

Thanks,

Greg
