What you will be doing is operating the computer in a mode called 'headless'. You will not be able to display anything from the computer operations, either, and will have to set up your computer by VNC or SSH tunneling into your computer and signing on on a different machine.
If you are controlling the media with remotes, why not just remove the keyboard and mouse after signing in and running VLC? It normally won't hurt USB devices.
