[fw-mvc] Navigation, Acl and AccessManager Action Plugin

I there:

I need to integrate Acl into Navigation, as in the manual:

$this->navigation()->setAcl($acl);

I'm using monzee AccessManager Action Plugin for the Access Control List:
http://code.google.com/p/mz-project/source/browse/trunk/modules/admin/controllers/helpers/AccessManager.php

This Action Helper build ACL based on the request, so no all resources are
loaded.
To load all resources I've to query my database about all record.

Is this Action Helper obsolete? (the project last update is on May 28,
2009).

How do you manage yours ACL?
