Is there a vagrant or docker install for simple developer experimentation?

It would seem there is.

These guys appear to be on the ball, usually a cursory investigation would lead me nowhere but they've got a healthy presence in all the right places.

The linked DockerHub repository does point to a page with an example Dockerfile using node-0.12, but they do have tags for 4.0 and 4.1. Fascinating.

thanks! we don't sleep...that much ;)

To me that means plenty of sleeper bugs ;)

Docker definitely on our roadmap; vagrant in consideration. It's a straightforward install for the runtime now.
