Given that we still don't have phones that last more than 12h of serious usage and a big issue with xmpp was that it drained battery by not using push... Local P2P on mobile phones is really not something I expect people to use. Android went fancy with opportunistic deep sleep not that many years ago - this would undo all that effort.

Just for the record, mobile XMPP clients pretty much all support push notifications these days. But you're right, this is possible because XMPP isn't pure p2p.

I'm similarly unconvinced of the suitability of pure p2p with (at least the current generation of) mobile devices. Maybe advances in bandwidth and battery technology in coming years will make such protocols more feasible for general use.
