Screensy - Simple peer-to-peer screen sharing

Screensy is a simple screen sharing solution. It consists of two parts, the rendezvous part which runs on the server, and the website part which runs in the user's browser. The rendezvous server is only used for protocol negotiation and discovery of viewers. The video stream is directly sent from the browser of the broadcaster to the browser of each viewer. All traffic (between rendezvous and browser and between browsers) is encrypted by default.
