 * we assign a etherpad group "etherpad001". In order to view/edit
 * the node 103 using etherpad, one would first have to first know the
 * etherpad001 ID before he can edit anythign. The whole user-based
 * authentication takes place on drupal level and only authenticated
 * users can get as far as getting the ID of the group id and hence
 * get read or readwrite access to it.
