Hi, Chris, there is no new document yet. I mentioned in my last post that an update to the ESM document is underway, and should be available later this year (2014). There's a lot of development and testing work going on to make the next generation a vast improvement on the first, so we appreciate your patience.
There are no other guides available right now, either internally or externally. We're hearing the demand for this loud and clear, and we're aware that the demand is great.
