Thanks Chris, it's great to hear that Cloudman worked well for you!

There actually is a way to launch an instance providing a share-a-cluster
string in user data for a while, (a `share_string: <stuff>` entry in user
data) but there is, or was -- I need to test this again, a race condition
in the boot logic that would sometimes have the instance go belly up on
