I think I am missing something here. What is the use of this? I mean, if 
it is not JSON, then it is "just" some random binary format, right? How 
does that help with parsing and providing JSON when you are 
communicating with a webservice, for instance? I mean, it is cool to 
have a file format that is able to contain a lot of standard stuff and 
be quick about it, but I don't really see the connection with JSON, and 
calling it a binary format of JSON is confusing to me.

However, like I said, I guess I am missing something here. Could you 
explain what the relationship is between this binary format and the JSON 
format, and how it helps parsing & creating JSON?
