You can write a generic script that can apply to a large number of users. For example, a simple screening app. A CPL interpreter platform would need to know to associate groups of users with that one script. But, this is not a CPL issue, its an implementation issue (and ours is indeed capable of such).   There are even other use cases where CPL scripts are never even stored, but rather generated dynamically. It all depends on how creative you are with your implementation.   -Jonathan R.   --- Jonathan D.
