A way to easily audit the image to ensure there's no 'special sauce' you left in. I realize it's no small feat, but I'd be a lot more likely to trust and use such an image if I had a way to make sure it's clean. (One way is to automate the process by way of script(s) that you leave up to the user to understand and review, whether they're Chef or Puppet or whatever else.) Related to someone else's question, it would be great to also be able to use these images locally for development (e.g., via Vagrant, even if another step would be needed to import the images etc)
