I've been pursuing something like this for transferring content between 
frames. That's part of why I was excited to see Web Intents taking off.
I also went with a ping mechanism for messaging.

I recommend taking this thread over to the Web Intents list and 
examining it there. I see every reason to want a loose idea of what Web 
Intents over postMessage would look like.
They have a shim mechanism for demo purposes and backwards 
compatibility, but they don't have the same focus you do (or I do), on 
iframe postMessage.
