They do it by using an asynchronous protocol. RTMP is the same protocol used by Flash Media Server and Connect. The server keeps track of registered connected clients, and broadcasts messages to all of those clients. You can approximate this functionality using AMF and polling, which is what the Messaging component of BlazeDS uses. You don't get messages immediately, though, since it's client-pull rather than server-push.
