It doesn't seem to be a P2P system, since it requires a server. According to the docs, "This server does not rewrite the messages or do much of anything besides pass the messages between the participants" [1] , so it's not really P2P.
I'm fairly sure the Firebase requires a server too... (their server, or else they couldn't charge for it).
