Running RemoteEye within a local network

  • Is it possible to run RemoteEye server on a local network, without using Internet at all?
    I've noticed this topic, where the reply looks like "you just need a general-purpose basic server to run RespondEye" which looks very promising to me.
    Is the RemoteEye server software free? How do I get it?
    The comparison with Hololens 2 says that X2 MR Glasses is "open source"... Is RemoteEye server open source as well?
