Not sure what your the data you are using looks like, but itsoulds like
in the fill method to your Data Management Service youcould pass the
share name. Then when updates are made users willonly get data
associated with their share. Does that help you? Also, if you are using
messaging and not the data managementservice, you can control who gets
what messages using selectors orsuptopics. See the developers guide for
more info. Hope thathelps.
