Use an LCD TV for the display and run the screen with a cheap computer with HDMI output and a web browser. Have the computer pull the data from some other computer running Filemaker for an easy to update database for the display. You can set up Filemaker to serve the list as a web page and update the display remotely from the serving computer. You could set up any number of displays accessing the same directory database via web browser.

Kind of a hassle to edit the video loops, but they like splashing propaganda all over it. We also have Kiosks all over the place that are used to clock in/out and record job information that displays various .png files for news/info when idol.
