[Zope] Sharing Database connections and/or methods between Zopes?

I have a database accessed with ODBC on one server (win2K) using just HTML tools to get to it with a working application. There are also other Zopes on this server but not connecting to this database. I then have another server, our primary site - in Zope, and I would like to get to the data on the other server. Attempts to just 'point' the ODBC DSN fail. Is there any way to have one Zope's ZSQL methods point to another Zope's ZODBC connection? Or something along those lines? The regular data app will be moved to Zope but the time is not there right now. Looking for a quick fix. Would xml-rpc handle that? One Zope calling another Zope's ZSQL methods?? Thanks Allen
