Basic Broadcaster (bb) allows you to transfer text messages simply from one computer to another on a LAN. The messages are broadcast in the LAN and and can be received by each machine running bb. No setup is required other than starting the application. The messages are transmitted as plain text, and no encryption is done. The broadcasts can only be sent to machines on the same subnet as the sending machine, and will not be forwarded by routers to the Internet.
