In the mean time here's how I've worked it. I do have the Role Manager plugin installed. Then, on the content that I want to show based on user class, I use the following:
if($user_level > 1 )
if ( wp_list_pages("child_of=".$post->ID."&echo=0") )
If you were the supreme administrator ($user_level == 10), you were the only person with a $user_level == 10, and you wanted pages to only appear for you, all you would need to do is change the if($user_level > 1 ) statement to if($user_level > 10 ).
Whatever code goes within the if statement (e.g., this works within the loop too) will only show IFF the user exceeds the needed $user_level. Other operators of course will work (e.g., <, <=, >=, ==, !=).
