[otrs] MOTD in customer login?

Hi, We would like to be able to give customers a status message if some major downtime is ocurring. When they login to OTRS it would be nice to let them know that "file server 1 is down, you don't need to create tickets to that effect". Also it would be nice is this message is displayed to users already logged in. I've spent some time trying to get MOTD to display via CustomerLogin.tt but my skills are obviously not up to the task. Is there an easy way to do this? Preferably the contents of the message should not come from a file on the filesystem but somehow be configurable from within OTRS. That last part is clearly in the nice-to-have category, though, and not a necessity. -- Lars
