Hi all,

I want to develop a classroom teaching web application which could work like a whiteboard. There is a server and clients for teacher and student. The teacher and the students will have a tablet each. I want the teacher's screen to be transmitted live to the screens of all the students. How can I accomplish this using HTML5, JavaScript and PHP? Please note that The teacher is also a client. A session will be maintained for all the clients who log in to the server. Please help me in any possible way.
