Streaming, I take it. If you want to send something out on your LAN, accessible to many clients without any additional load on the server, use UDP multicast. On the server you plug in a multicast address in the Stream Output window (you don't have to change your actual server PC's address). The clients then do an open network stream.
Quick and dirty: put in 239.20.30.40 as the Address on both the client and server UDP setup windows. Multicast by definition goes to everyone in the local segment, one copy of the stream that anyone can choose to listen in on.
