My delima is as follows:

my boss wants me to put a module (lets say the Announcements) on a
page.

He then wants me to display that module based on security level: IE
user level one sees Announcement_1
user level Two sees Announcement_2 etc

I don't really see any way in the codebase [or i should say i haven't
found] to add a module programatically to the page, or even a way to
alter the module ON a page.

What I was thinking of is as follows :

Creating a seperate module instance in the DB for each user module.
Checking the user security when they hit the page
Displaying the appropriate module.

So, in a nutshell .. can anyone point me at a controller etc that I am
missing in the DNN objects that I can use to either programatically
insert a module on a page, or change the module that is loaded into a
'placeholder' module ?
