+1.

On the side: I know a <big unnamed company> uses streaming state 
transfer to do this. Not really the way it was designed for, but it 
works well for them.
Here's the link: 
http://www.nabble.com/Streaming-Message-Transfer---td14476343.html. The 
3rd posting from the top describes their approach.

I still think though that JBC implementing this via chunks would be the 
better solution.
