I know node better and would be a bit light on other frameworks. Do you have suggestions?

Throw across your node work. I will try to replicate the same for RoR. :-)

When I post the implementation notes for Node, feel free to speak up with the RoR speak for that item and I'll add it in.

Thank you.

I'd be happy to try and do a Python version of this. I'm most familiar with Pyramid, but Flask and Django would be a learning opportunity for me. Much of this advice I've already implemented in Pyramid.
