Great, looking forward for your feedback.

There’s nothing wrong with Briar, it just has a different positioning. MTC is a balance between standard rich multimedia real-time messaging, including audio/video calls, and privacy (full peer-to-peer). Briar’s design, Tor when online, Bluetooth/Wi-Fi mesh when offline, limits the possibility of a full messaging experience (WhatsApp-like), but it’s strong on metadata hiding, and its target users are different (activists and journalists in hostile or censored environments, etc.). MTC’s target users would be standard messaging app users with some more attention and concern about protecting their private conversations, without giving up all the standard messaging features they’re used to. By the way, I’m working on implementing the Bluetooth option.
