Actually CakePHP's ACL is capable for row access. Please refer to http://aidanlister.com/2009/05/implementing-row-level-access-control-in-cakephp/. But personally i dun like this approach. I may look into the Permissionable Behavior of jmcneese ttp://jmcneese.wordpress.com/2010/01/28/rmac-is-dead-long-live-rmac/ for my next project.
Hope the 2 links above help you and willing to see how cake community deal with row-access efficiency :)
