Ok. Since I want to try and keep this with a low barrier to entry, I'd
prefer to avoid making people install p9p, which I think is what you
said is needed to do auth. I tried 9mount as well and had no luck
there--"permission denied" when I try to mount.

Is it possible to just export one directory without authentication? I
want to do read-only access if possible... is that what you get as
'none'?
