OK, this is, I think, ill-advised. Compression of XMPP by means of binary XML?
"You got your binary in my XMPP!"
"You got your XMPP in my binary!"
However, unlike peanut butter and chocolate, these are two great tastes that go horribly together. Something like, say, broccoli ice cream. Ick.
Furthermore, this document is full of misunderstandings about the nature of XMPP -- the kinds of traffic it carries, the ability to scale XML streaming, and the like. I'll have to straighten some folks out on this score, because I sense a solution in search of a problem here....
