I've been mulling over an idea of using an RSS feed to automate this process a little more, and allow for the possibility of putting the information other places as well.
Essentially it would be a program that allows you to input current and future announcements, and select where they will be published to. They could go to the print version, the website, a PowerPoint style flatscreen inside the entrance to the building, and/or the pixelboard outside. I assume that there might be some editing of the print version required, and of course the pixelboard is not connected to the Internet, but there are people manually inputting those anyway.
Just an idea, what do you think?
