It would be great if we could have an area where an admin can post Important Announcements and have them display in the Header for the entire jitbit site.

To expand it could be configured to only display a message when someone from a specific company or even department logs in to the system.

This would be great to announce a service outage or Product Update.  For Example: "major problem with widget A. Please click here to download new firmware" or "The Finance Server is Down.  We are actively working to restore service to the financial software"

It should be able to accept HTML.  When there are no announcements it should be invisible or display something that is admin configurable for example: "No active service interruptions at this time"
