Filter view based on TAC

Here's what I ended up doing. I added some custom code to the Argument Handling Code for the view. This code first checks to make sure the user is not uid 1 (drupal admin). If not then it gets all the roles that the current user has. It then queries the term_access table to get all the terms that the user has "update" access to. Finally, it assigns those terms to a filter for the view.

Hopefully that makes sense. The code I used is listed below:

global $user; 
if ($user->uid!=1){
  foreach (array_keys($user->roles) as $rid){
    $ridQuery .= "rid=$rid OR ";
  }
  $ridQuery = rtrim($ridQuery, ' OR ');  
  $result = db_query("SELECT DISTINCT(tid) FROM {term_access} WHERE grant_update=1 AND ($ridQuery )");
  
  $value = array();
  
  while( $row = db_fetch_array($result)){
    $termValue[] = $row['tid'];
  }  
  
  $view->filter[] = array(
    'vid' => $view->vid,
    'tablename' => '',
    'field' => 'term_node.tid',
    'value' => $termValue,
    'operator' => 'OR',
    'options' => '',
    'position'  => 0,
    'id'  =>  'term_node.id'
  );
}
