[development] Even more flexibility in content management

'view' is already one of the options fed into hook_access(), so in that 
sense this set of permissions already exists--it's just not implemented 
(yet) in the core node types. If you wish to implement it for a custom node 
type, you can define perms 'view whatevers' and/or 'view own whatevers' in 
hook_perm().

Then:

/**
 * Implementation of hook_access().
 */
function whatever_access($op, $node) {
  global $user;

  if (user_access('administer whatevers')) {
    return TRUE;
  }

  if ($op == 'view') {
    return (user_access('view whatevers') || (user_access('view own 
whatevers') && ($user->uid == $node->uid)));
  }
  ,,,
}

> "administer TYPE content" - roles that are allowed to modify the 
> publishing options on all nodes of that content type

This could be done in a contrib module for 5.0. Something like:

function adminnodetype_perm() {
  $perms = array();
  foreach (array_keys(node_get_types('names')) as $type) {
    $perms[] = "administer $type content";
  }
  return $perms;
}

function adminnodetype_form_alter($form_id, &$form) {
  if (isset($form['type']) && $form['type']['#value'] .'_node_form' == 
$form_id && user_access( 'administer '. $form['type']['#value'] .' 
content')) {
    foreach (array('author', 'options') as $key) {
      $form[$key]['#access'] = TRUE;
    }
  }
}
