Interesting and timely article! On an Ubuntu guest (Windows host), I install the Samba server and then use the native Windows CIFS client to connect to the Ubuntu host. This gives me the advantage of vm (virtualbox) native filesystem and letting me use my windows machine to open files on the guest
Perhaps this support can be added to some later version of vagrant
This is what I would do when I was on Windows. The biggest (really big) downside is that the files live inside the VM and are only accessible when the VM is up and running.
