Re: Using HTML5 Channel Messaging with Web Intents to create persistent relations

So, my understanding is that if developer wants to have persistant
connection
within "CURRENT" WI framework, exchanging servicer's url via postResult()
and creating persistant connection with postMessage() / MessageChannel()
by it (under iframe basis) will be required.

Is it right?

Year I agree that it seems complex procedure, But it is worth to take care
of.
Because it realizes user controllable Mash-up sites :)
