Some room settings to have a little more privacy in networked servers.
http://janusvr.com/docs/build/roomtag/index.html#Room
cursor_visible - (default "true") - Whether or not to display other users' current cursor position.
party_mode - (default "true") - Whether or not to allow users to broadcast the room on the JanusVR "party mode" server. With this attribute set to false, even users who are currently in party mode will not be able to transmit their location. However, users may still tell others, or may be using a client which does not honor these settings. If you want to truly secure your webspace, consider using a password defined in the .htaccess file of your website. Tip: Don't want the world to see the room you are working on yet? There is a way to disable 'Party Mode' broadcast from your room, and also stop it being added to the 'popular rooms' list In the tag add party_mode="false"
