Then site1 should look something like this:
$databases = array ( 'default' => array ( 'default' => array ( 'database' => 'mysites', 'username' => 'user_db', 'password' => 'password', 'host' => 'localhost', 'port' => '', 'driver' => 'mysql', 'prefix' => array( 'default' => 'site1_', 'users' => 'shared_', 'users_roles' => 'shared_', ), ), ), );
All of the sites would use the same (mysites) database. Each site would prefix all of the tables that it did >not< share with <somesiteid>_, and user a common prefix — I like shared_ — for the ones it did.
Obviously, each shared table needs to be individually enumerated, so that list can get pretty long in some scenarios. I have sites that share 150 tables.
The gotcha is that the table list changes when you add or update modules and content types, so you need to stage any changes and update the settings.php files before you make the changes in production.
