Are you sure about that? http://developer.android.com/google/gcm/index.html http://developer.android.com/google/gcm/index.html talks about using XMPP upstream but I thought the protocol to talk to the device was a lightweight proprietary thing.

It is. I talked to one of the devs a few years back, and he explained how they used [Protocol Buffers][1] internally, because XMPP just didn't work at their scale. XMPP is a protocol that Google uses in some instances to talk to the rest of the world. But inside their ecosystem, they have no reason to stick to it.
