Why is Windows not supported? What is necessary?

This was what I was looking for as I pull my hair out with virtualbox :)

Simply because I don't know how Vagrant works on windows. I don't have a windows machine to develop support for it. If you look into the code, you'll find that I'm relying on the .vagrant directory inside a vagrant project directory to find information about the state of the VMs. I don't know if Windows has that directory when vagrant is initialized. Also, I do make use of the vboxmanage command. Not sure how to call that on a Windows machine.

Someone with some Ruby skills and a Windows machine should be able to add support without too much fuss.
