Thanks for the replies Rob. I am interested in testing mainly because not a lot of projects have spare clusters lying around for performance regression testing. But then these days we can get machines from EC2 easily & relatively cheaply, so I was wondering if other projects are migrating their test infrastructure to EC2.
