It sure would be. My main reason for exploring this was to learn how
to do it, not necessarily because it would be a good idea to actually
do it.

Thanks for the explanation, it answers a question I hadn't asked yet:
I was wondering why the usbfat: script starts a new dossrv (posting it
under /srv/usbfat.$user), rather than reusing a possibly already
exisiting dossrv. (One of) the reason(s) is that the files in /n/disk
it needs most likely aren't available to any existing instance of
dossrv.
