[development] Multiple user aliases - Multiple user node, ownership

[Scott Reynolds]

My approach did not involve just the node_access table, it used the og
table  (to determine if the user is an admin of the group). Just get rid of
the og stuff and put in your node_uid table

So revised using node_uid table like as follows

hook__node_access_records()
  // add the admin access row
 $grants[] = array(
   'realm' => 'node_author',
   'gid' => $node_uid_record->nid,
   'grant_view' => 1,
   'grant_update' => 1,
   'grant_delete' => 1
 );
 return $grants;*

* hook_node_grants()
foreach ($node_uid_records as $node_uid_record) {
   $grants['node_author'] [] = $node_uid_record->nid
}
return $grants

I have done the same in the ejournal module, but what is not possible
