I believe I could write it myself if:
1/ I had access to an AWS account. Can anyone help in this regard?
2/ Someone just told me what's missing in the current image. Adam, could
you give a quick summary of what's needed?

Since both OpenStack and AWS are using the EC2 metadata server, I'm
convince that it should be possible (and even desirable) for Debian to
ship a single image that would accommodate both. I'm willing to do so.

Cheers,
