I would love to have node and private server on the phone. But I’m looking realistically to that applying to real life and I’m very skeptical its possible in the nearest future

Especially given the fact how mobile networks routing work, this is the main issue today, not even battery size

Lets say I only use LTE today, which IP address should my phone expose without any centralized signaling services? Last time I checked it wasn’t possible. P2P doesn’t work today. Thats actually the reason why nostr works as it works
