This got me thinking and while I don't have the time to do the work
I can see a somewhat simple solution to this via a plugin. What I'd
do is design a plugin that:

   (a) contained a method that returned a set of pages based upon
       a regex matching of page name
   (b) set the ACLs of those pages to a parameter supplied by the
       plugin, since from the plugin one has access to the
       AuthorizationManager and AuthenticationManager.
   (c) was somehow constricted by authorisation, etc. so that it
       couldn't be abused. Conflicts between multiple instances of
       the plugin would have to be mitigated somehow.

Most of the above doesn't seem too difficult. The hard part would be
(c), keeping this from being abusedm and solving conflicts.

Any ideas further to this? Seems like a possibility anyway...
