Sharing directories from Windows hosts

I'm running QEMU on a Windows host with multiple Linux guest VMs. I'm trying to share a host directory with all the guests.

As I understand it, the way to do this with Linux hosts would be to configure a 9p share[0]. However, it appears that 9p support for Windows hosts is currently a work in progress[1].

Is there another common option known to work for Windows? I would guess something like running a users-space NFS server might work, but before I went down that rabbit hole I wanted to see if there's something built into QEMU that would be better.

Bonus question: once 9p support is implemented, would that be expected to have better performance than something like NFS over a QEMU slirp network? I need to use slirp because I don't have admin privileges on the host.
