My point was that the architect can define the passing of data within a system using "types" or "topics" or "classes". Those data values originate from certain entities and are consumed by certain entities. By deploying a security based pub/sub space, the architect remains in control of data flow design, in a seemingly adhoc data flow world. Only the authorized uses will be able to happen. All other uses will not be allowed and the developers will have to stick to the systems architecture/model. Gregg Wonderly ------------------------ Yahoo!
