I think the reason #1 doesn't make much difference because we still have an interface which is independent from any transport implementation. I don't have much idea how message chunking will be implemented, so I'd like to listen to more idea on it. At least, I'd like to remove limit and position from MessagingBuffer, and it will only simplify the implementation IMO.
