392738 A ChatRoulette Clone

We need you to develop a [login to view URL] clone. The only difference between our website and the original chatroulette is that we want to offer our users a drop-down menu with room names. Once the user selects a room from the dropdown menu, he or she will only be connected to a random user that has selected the same room. Otherwise the design and functionality has to be the same as at chatroulette, basically a one page website. Please notify the technologies you would use and if you know how it is done at chatroulette.com.
