LANMessage

LANMessage is a little program that will pop up a translucent window with a message in it across your LAN. I use it to display caller ID information on all my systems as it comes in from my answering machine (which is a software program running on a Mac). Right now, it's Mac only - I've had a real struggle trying to get it to work on Windows too.
