+>* I'm only thinking about write ACLs. As Joey noted, read ACLs need to be done in the web server.
+>* ACLs are going to be really hard for people with direct access to the revision control system.
+> Which means that we really only need to define ACLs for web access.
+>* ACLs for web access can then be defined by the web master. These might not need to be
+> defined in the wiki pages (although they could be).
+>* Given the previous two points, can't this be done with the `match_user()`
+> function defined by the [[plugins/attachment]] plugin (see the [[ikiwiki/pagespec/attachment]] pagespec info)
+> and the [[plugins/lockedit]] plugin?
+>
+> For example, add the following to your config file:

+> locked_pages => '!(user(john) and */Discussion) and *',
+>
+> would lock all pages unless you're john and editing a Discussion page.

I am considering giving this a try, implementing it as a module.
Here is how I see it:
