mobile first is more than just availability but battery use on devices for which ipfs has generally sucked, veilids onion routing will massively increase resource consumption so i will guess they will depend on dedicated data center nodes, so much like the fbi now runs most of tor
p2p is littered with failures and why nostr is not using it 'yet', holepunch seems the most promising attempt in a while
keet is planning blind forwarding for availability so friend relaying, and they have some new notifications system
