The Transients API[1] would potentially be something that persistent storage could be based on using hooks.  

But alas, it is loaded *after* advanced-cache.php and it depends on the hooks system, which is loaded even later.  Yet another example of how caching is hard to implement in WordPress because core has never needed to address these issues.
