This Chrome extension is developed primary for 인맥.com. It doesn't do anything except capture content of your screen.
This chrome extension allows you share screen of any opened application, privately, securely between maximum-256 users. Quality of the shared screen is full-HD i.e. 1080p. Remember, everything is peer-to-peer. Nothing is stored on the server. WebSocket is used only to connect two users at initial handshake.
