Hey Justin, is this what you are looking for: https://github.com/Microsoft/docker.

This is where the Windows team is doing the work to add Windows Server support to the Docker engine. We are working with Docker Inc. to plan the PR up, once it is ready for primetime.

Note, I am an engineer in the Azure team...

Thanks for the link - I checked out the master branch and it didn't have any real diffs on it. Which branch should I be looking at?

Hi Justin, We are doing most of our working in a branch right now (https://github.com/microsoft/docker/tree/jjh-argon), as we stabilize the Windows Server Container and Hyper-V Container foundation the work we are doing to develop new drivers into the docker engine will stabilize and we’ll be pushing it upstream.
