On hacker news I'd suggest sharing some technical choices, otherwise you leave people to guess. Anyway: 1. Looks like you're not using libp2p, why? (Not accusing, just wondering) 2. What is your fallback mechanism when hole punching isn't possible? Relay nodes? 3. Follow-up: how do you ensure an acceptable QoS (latency, bandwidth, time to peer-discovery etc) for that fallback mechanism? 4. How do you handle many participants? Amount of chatter scales n^2 by default in p2p. 5. What application bundler are you using (eg electron)? 6. Bonus: what technical challenges were hardest? Any big unsolved problems? Thank you.
