Re: Client to client communication

A GWT client is a web page in a browser, which can't talk to another browser instance, because a browser can't listen on a socket, as far as I'm aware. So clients don't really have 'port numbers'.

I think that the right way to do what you want to do would be to have clients send messages to a server side queue which would store the messages until a client polled the server for messages addressed to that client.
