Let's see if someone in the StormGrind forum knows about this. Moving this thread there.
Unfortunately I'm not sure about the activation. I can propose you to take a look at CirrAS – this is a JBoss AS deployment in the cloud, including Amazon EC2 which should help you!
Well, I posted through RH's sales (was the only channel I could get to) and eventually they got back to me with some language that sounds like there was a problem and they fixed it. But I've already cancelled and moved on.
Thanks for the info.
