TogetherJS : a real-time collaboration tool
Once again Mozilla made a future hit ! TogetherJS is a service you add to an existing website to add real-time collaboration features. Using the tool two or more visitors on a website or web application can see each other’s mouse/cursor position, clicks, track each other’s browsing, edit forms together, watch videos together, and chat via audio and WebRTC.
Plugins already exist for WordPress and it’s easy to integrate in any website :-). Well done Mozilla !
