Very cool, but there's one thing I don't understand.

Do you need to stream JSON objects from a server to make this work? You have to get a response from the server in some kind of streaming protocol right?

Or...

Is this just reading the part of the JSON string that it currently has?

I'm inexperienced with streaming, so this might be obvious to some.

EDIT:

Ah, I get it. I was wrong to say it was "streaming". Looks like my second suggestion was the correct one.
