   1. Allow themes and other plugins to tell W3TC who's served fresh pages. Add the following lines after the first conditional of _can_cache() of PgCache.php I think it's at line 354.

   $dont_serve_cache = apply_filters('w3tc_dont_serve_cache', $dont_serve_cache, $this);
   if (!empty($dont_serve_cache)) {
   	$this->cache_reject_reason = $dont_serve_cache;
   	return false;
   }

   Example use: Always serve fresh pages to those who have a certain cookie.

   2. Allow themes and other plugins to tell W3TC what pages are never saved to cache. Add the following lines after the first conditional of _can_cache2() of PgCache.php I think it's at line 429.

   $dont_cache = apply_filters('w3tc_dont_cache', $dont_cache, $this);
   if (!empty($dont_cache)) {
   	$this->cache_reject_reason = $dont_cache;
   	return false;
   }

   Example use: Disable W3TC Page Cache during weekends.

   Thanks, fredericktownes!

   Allow themes and other plugins to tell W3TC who's served fresh pages.

   The proposed implementation is unreliable because when _can_cache() is executed, WP core has not yet loaded so apply_filters() is also not available.

   Allow themes and other plugins to tell W3TC what pages are never saved to cache.

   A DONTCACHEPAGE constant is already available in the next release.
