Hey subsection1h, I'm Ryan from Ninefold. We're working on getting our docs in place around multiple environments. Our setup is different from Heroku and they do a great job of describing why you'd want more than one environment, so I think our article will be much different, but I'd like to make sure it's informative.
Is there any specific information you'd like to see in there?
Also, we use Phusion Passenger to manage our deploys and we do implement pre-start: http://www.modrails.com/documentation/Users%20guide%20Apache...
We're working on a new feature to further reduce the chance of diminished performance during deploys. There will be information about it in our docs and on our blog as soon as we release it.
Thanks, Ryan Clark Lead Rails Support Engineer | Ninefold.com
The first thing I looked for was support for multiple environments (e.g., staging and production). I searched ninefold.com for "staging" using Google, and there weren't any relevant results:

After not finding the above two features, I stopped looking for other features that interest me.
