From the developer: "LAN messaging software. Send non-obstrusive alerts, warnings or messages to designated users/machines (or to everyone). Text may be linked to online documents. You may even target existing NT Domain groups. A complete system comprises 4 modules: The Pigeon Server which runs as a service (or service simulation under Windows 95/98/ME), the Pigeon Clients (free), the Pigeon Admins (free) and the Pigeon Generator (free). This last one permits machines and/or processes to generate messages (available for Windows and Unix)."
