UDP Chat
Network text chat (instant message) app requiring zero configuration
...Because this script uses UDP, anyone who runs it on a local network will automatically receive messages broadcast by others on the same network. A separate server program and/or connection(s) to specific IP addresses are NOT required. A "who's online" function is included to list all currently logged in users.
An MS Windows .exe is provided. For other OS platforms (Mac, Linux, and others), just download the Rebol/View interpreter and run the udpchat.r file.
