I use webdav for serving media over tailscale to infuse when I'm on the move. SMB did not play nicely at all and nfs is not supported..

The go stdlib has quite a good one that just works with only a small bit of wrapping in a main() etc.

Although ive since written one in elixir that seems to handle my traffic better..

(you can also mount them on macos and browse with finder / shell etc which is pretty nice)
