How can I mirror a screen from one Linux device to another, without using the Internet, using VLC Media Player?

I have two Linux devices (a laptop and a tablet), and I need to mirror the laptop’s screen to the tablet over a network. (The laptop will be displaying a LibreOffice Impress slideshow, and I will be able to control it using a wireless keyboard, but I will not be able to see its screen while speaking.) I will have a Wi-Fi network available, so the devices can connect, but it may or may not be connected to the Internet. Is it possible to do this using VLC Media Player? If so, how?
