title: set up websocket on hostgator with shared hosting
body: <p>I would like to try to use the HTML5 websockets API to create a video chat app.  I understand what to do on the client side, but I don't know how to set up the server side.  I am currently using shared hosting on hostgator, I am wondering if I can set up websockets on my server without upgrading to VPS hosting or a dedicated server.  Also, the server limits the number of processes running to 25, does this mean then that if I do set up a websocket, I can only have at most 25 users using the chat application.  If this is not possible, then I would like to know any cheap alternatives.</p>
