I know it is possible to post crossdomain and to different tabs.
Example here: http://html5demos.com/postmessage2
But this it only viewable by 1 user. The person who is posting the message.
Is it also possible to use postmessage to a remote machine e.g. other user?
Or that anyone who goes to the page which has the eventlistener on it will actually see the posted message?
Is this possible?
