>Framasoft also announced that next year they will bet big on PeerTube, working on features such as better moderation tools, working on promoting the ecosystem more, and an official PeerTube mobile app.
And on another front of the mobile battle, podcasting 2.0 apps are increasingly supporting PeerTube video via the RSS feed.
That's the p2n layer that already exists in PeerTube through the redundancy feature in federation.
Federated instances that enable redundancy copy all resolutions of a video that meet chosen criteria of popularity. When a user views the video on PeerTube, their browser grabs the sections of the video from any of the PeerTube instances that have a copy, creating an ad-hoc distributed CDN. This covers the mid-level of popularity and keeps the hosting instance from getting slammed on bandwidth.
If something goes viral, or during livestreams which are by nature simultaneous, then the p2p in the browser between viewers kicks in and reduces load on the peering servers even more.
