PHBB Has An Easy Way of Using Multiple Boards and One Userdatabase.

So why is there no easy way to do something like this



I have been looking for a way to share one user-database with multiple forums/licenses on the same server but we dont really have any in VB 3.5. basically I want to be able to instal multiple forums under 1 domain and integrate it with an existing board because I need to have thousands of forums and sub forums . See This If You are Confused
Anyway I found out that Invision has a Log In Authentication Manager module that lets Admins select a method to authenticate .

How hard would it be to do something like that . See Attachment of IPB Admin Control Panel below
