So once again, how would you answer Roger's question ? Suppose changes were made on both computers at the same time. How would you reconcile the two copies of the databases ? If you want to use the copy from the computer to /update/ the copy in the mobile device then the mobile device needs access to /both/ copies of the database when it's doing the updating, so it can see what's new. So you really have not one database but two databases.
