I actually like the idea of using ACLs (Access Control Lists) in conjunction with groups. For each forum you can add a list of users individually by name or use group names (which contain individual names). Each entry in the list could then nbe assigned the "tags" you refer to in your post.
So, for Forum A I want to have it open to the public and accessible by ALL. There could be a special group name that contains ALL users. This woul dbe the default lets say. Then if you wish to restrict access to a select group of users, you could only list that groups name in the ACL and then add people to the group when you wish to add people. With this type of system you could have read only for ALL users and then include a group for individuals who you wish to be allowed to post. So it essentially becomes a read only forum but a select group gets to post messages.
This removes the "Level" altogether which I believe would be a good thing.
Just my .02 cents! <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" />
