Michael, I'm not sure I follow -- I was literally thinking in the sense of "what values do I put in my persistence.xml / hibernate.cfg.xml file to get this app to connect back to that particular singular datastore?" for each of my 3 or 4 apps that want to share that same singular source of data -- basically what the JDBC settings would be.
Creating a public API that is exposed via web services or something is fine/great/etc -- just not the use-case I needed. Maybe it was a dump question and the nature of the GAE beast is that 1 app gets 1 data store and everything is sandboxed just by virtue of how the system is designed/intended... I might just be thinking about this wrong. Also, Merry Christmas and Happy New Year to you as well!
