Network Aware Screensavers?

borgquite asks: "Does anyone know of any network aware screensavers? I am running a school network and would love to be able to have a screensaver where the other computers communicate with each other in some way - for example, if you could have a marquee where the message gets passed from screen to screen. The best I can find is n 0 time, but is there anything else a bit more exciting?"
