How would I spin up multiple Docker images in a load balanced cluster...do I need to pass 2 sets of differentiating lister ports on each docker image

Yes, you would need to give them different `--publish` options so that they don't both try to claim the same host ports.

What about support for Microsoft's new container technology?

Microsoft hasn't announced docker support yet, so we'll have to wait and see. Since the script is fairly Linux specific, I don't imagine it will work in a Windows container without a lot of work.
