Hmm, I haven't heard before about GTalk on Android using Protobuf (not 
that Google has officially given any detail in either direction).

But if you look at the "GTalk Service Monitor" app (open the phone 
dialer, and dial *#*#TALK#*#*), you'll see mention of iq stanzas, the 
device JID, and Smack "SSLXMPPConnection", which all sounds pretty XMPP-y.

(Not that this necessarily proves that regular XMPP is actually sent 
over the wire)
