@rclilly Sounds promising. The changes in [my `feature/gather-hosts` branch](https://github.com/simonwheatley/varying-vagrant-vagrants/tree/feature/gather-hosts) are aimed at allowing hosts to be added dynamically by files or whatever, rather than being manually added in the `Vagrantfile`. I'll add the request for Windows checks on the main thread of the pull request, so it's more visible for others.
