Could this be used to spin up older os x (and older Linux and Windows)? Or would any of the other services do that? Would be really nice for my work!

Anything that has a base Docker image available, this would work. RHEL, Debian, etc should work without much effort. I have not seen older OSX Docker images so probably not. Windows server does offer some base docker images.
