Thank you very much Mathias. I will review the information that you suggested about the Dispatcher. If any examples come to mind, I would appreciate it if you send them my way.
By the way, wrapping the streams is quite amenable to java coding so I foresee an easy implementation with that. Besides, I just skimmed over the DevGuide and there is a chapter on Database Access that may also be helpful: One can presumably connect to databases through JDBC drivers and such and there are classes to insert, update, and delete, records from XInputStreams.
