Thanks. As a hint for the next person, it seems like the asymmetric

I think there are two more cases. Because the messages are all async,
the 'it gets missed case" can be "it gets delayed". That causes
additional messages.
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.
