Using XHR to implement communication between documents is not possible because of the usual "original server only" restrictions. WebSockets is more appropriate as a communication layer, but we should be able to use other communication layers too. The problem is to establish communication, and then to pass messages, not just plain strings (although others have mentioned that the message part could be "externalized" to a JS library).
