Oracle Apps actually works that way, that a user gets assigned an organization id org_id when he logs on (not using trigger, from client side instead) and uses views which restrict queries & dml by org_id. This is based on session environment variables, I believe it's better in performance point of view, if we would have to scan a "privileges" table during every select on any table, it could become the bottleneck...
