Checking the search for multisite table prefix, http://drupal.org/search/node/multisite+table+prefix, you can find a few examples. Specifically see this page,http://drupal.org/node/22267. I believe you will need to reverse your thinking and make the default -> 'site1', and then list all the shared tables.
