a couple little filter snippets to expose some ppt permalinks, not quite desirable functionality yet

permalink_filter.php

<?php

if ( ! function_exists( 'add_key_to_the_permalink' ) ) :
/**
 * Try to automate using the special key by adding to permalink
 */
function add_key_to_the_permalink($permalink_url) {
        global $post;
        if ($post->post_status == 'publish' && !empty($post->post_password)) :
                $permalink_url = ppt_make_permalink($post);
        endif;
        return $permalink_url;
}
add_filter('the_permalink', 'add_key_to_the_permalink');
endif;

if ( ! function_exists( 'hum_edboard_posted_on' ) ) :
/**
 * Prints HTML with meta information for the current post-date/time and author.
 * Create your own twentyeleven_posted_on to override in a child theme

 * @since Twenty Eleven 1.0
 */
function hum_edboard_posted_on() {
        echo '<span class="sep">Posted on </span><a href="';
        esc_url(the_permalink());
        printf( __( '" title="%2$s" rel="bookmark"><time class="entry-date" datetime="%3$s">%4$s</time></a><span class="by-author"> <span class="sep"> by </span> <span class="author vcard"><a class="url fn n" href="%5$s" title="%6$s" rel="author">%7$s</a></span></span>', 'twentyeleven' ),
                esc_url( get_permalink() ),
