Fully encrypted, no numbers, no emails, no central servers, completely p2p, low latency video chat, file sharing (no size limits), streaming content directly from peers means you don't have to download before viewing, when you download something in a group you become a seeder so that other members of the group get it twice as fast. It collapses the separation btwn user & host so that everyone functions as both in some form or fashion. But really needs "super users" or like an always on home computer to anchor the chat. You will be able to set how much you seed or host in a more granular way in the future.
