Take a look at http://pushmodule.slact.net . You would have Java send
HTTP requests to urls of your choosing to interact with the server --
both to publish messages and subscribe to communication channels. If you
want any sort of moderation functionality, you will want to keep the
publisher locations visible only to your application and have clients
send messages through your application (which will implement your
desired moderation logic)
