Rendering a web page to two or more different users simultaneously.

Say, I have a web page and I want other users (chosen by me) to view the same web page. And as I navigate through the page, they see the same changes. Same as that when we share screens in Teamviewer. Is it possible in rails 3.2 or 4.x . If possible, how and what gems are needed?

You need to look into Websockets or any realtime backends like Firebase

Thanks for your reply.
