You can set FF flag APPEND_ONLY - all allowed write accesses are 
CREATE and APPEND_OPEN then. RC and ACL can do the same, and 
additionally allow somebody else different kinds of access.

So you can easily deny RENAME, DELETE and other write accesses. RSBAC 
does not have a "write_once" right, though, so that appends will 
still be possible.
