I think the easiest thing is to have a "background common read-only directory"

only few parameter needed:

background path = /home/common
background write_over = yes|no

all the files present here will be seen as read-only by everyone.
if you open the file read-write you may choose to either fail the
open or copy over the file to the user directory and use that file
instead.
In this situation only files _not_ present in user directory are taken
from the background dir, so that user created one are in "foreground".

Simo.
