What you propose looks very similar to the Cross-document messaging already included into the current draft:
http://whatwg.org/specs/web-apps/current-work/#crossDocumentMessages

The principal difference between this and your proposal is that you insist on the messages to be JSON. I rather agree with the current WHAT spec which defines just sending of strings back and forth without imposing more complex interpretation upon them.

Also, the current WHAT spec reuses the event handling mechanism in contract to introducing an ad-hoc one with send() and receive() methods. DOM event handling alows events to be dispatched asynchronously, which fits various threading models implemented in browsers better.
