> Peer to peer has been dead for more than a decade. Source? Some apps like bittorrent have increased in the past decade, have they not?

I shall say peer to peer in the context of legit software like video conference, not for downloading movies. Peer to peer simply doesn't work since NAT. Skype used to be peer to peer but they backpedaled a while ago because this and more reasons that simply made p2p obsolete and broken. It's too long to cover in one message. Would you be interested if I write a blog post? How peer to peer architecture became obsolete and why no software is using it.

  I would read that blog post in a heartbeat.

  If I am understanding the premise: In a scenario of 12 people video chatting around the world, I don't believe you could guarantee consistent high-speed connections between the involved parties.

    Making the connection is the hard part. The vast majority of computers and mobile devices basically do not have a routable/public IP address. Teredo tunneling was one of the coolest solutions to this problem, providing both NAT-busting and IPv6 support but unfortunately it never gained popularity.

  > Would you be interested if I write a blog post? How peer to peer architecture became obsolete and why no software is using it. Ya, I'd be interested in reading that! Could you address why it wouldn't work with NAT the same way bittorrent deals with it? I'm probably missing something, but I don't see why bittorrent can work so easily but video conferencing cannot. thanks Edit: Does bittorrent require you to port forward? I didn't think it did, but I haven't seen it configured in years so maybe I am forgetting that step

BitTorrent typically requires you to open a port on your router. For home use you just turn on UPnP but good luck getting that to work on a corp network.
