I'm as impressed by this as the next guy, but the one detail missing from the excitement is that this peering style requires Tor nodes to exist. "even if every relay went down, you could still connect to my phone!" Yes - as long as there are still Tor nodes.
This is an enormous leap forward for decentralized communications but I hope the next hop is in the direction of true peer to peer approaches that don't rely on Tor.
