Access role psml

[Burmeister, Mark]

Under the PSML directory there is a ROLE directory.
I want to be able to access that psml file from any user and update if from
the admin user. 
I have a handle on how I am going to do this but I have no idea how to get
every user to access teh same psml file to view a specific portlet that is
configured there.
I am trying make a messaging system where an admin can set a message for all
users to view message from the administration.
Any direction or ideas.
 
Thanks
Mark
