[Mediawiki-l] Access control

[John Yu]

I understand that an overhaul of the current access control is planned, 
which can put users and pages in access control groups. But this won't 
happen until 1.5 or later.

I'm wondering if I can easily implement access control based on 
Categories as an interim solution: pages belong to a specific category 
can't be viewed or edited without logon.

Is this doable? If so, which php files are the starting point I need to 
hack?
