Doesn't leak metadata, yet they say it's using direct connection? - Massive fail. Afaik, if you form direct connetion between Alice and Bob, you're leaking metadata and clearly revealing connection as well as communication times, amount of communicated, called communication pattern. If that's not metadata leak, I don't know what is. RetroShare has provided similar kind and even bit better features earlier. But with same limitations, it doesn't hide communication patterns and doesn't stop metadata leak.
