Peertube neatly solves part of those issues. * Storage costs are likely paid for by the uploader. Most regular uploader do (or should) keep at least a local copy of their work. Plus the original materials. So the weight of the video is likely not that significant. * With webtorrent, the more a video is watched, the more it is shared. If you want to handle the worst case though, you'd need enough bandwidth to serve a couple times every file over simultaneously. That gets worse the more videos you have, but simultaneous watching of every one of your videos is unlikely, I think, over a certain number. It would be nice to get some stats on this. * That's not really needed, is it? Latency isn't likely to be big enough to cause issues, and I would think available bandwidth doesn't change that much with distance. With a couple of local torrent peers, that also gets better. Now, this isn't perfect, but there are ways this can be improved: * Peertube intances can mirror content to provide at least one peer (and a backup HTTP source I think). It would be nice if subscribers could choose to support their favorite channels by asking their instance to mirror that content (with a lower priority than local content, of course). That could more or less solve the local CDN issue, if "peertubers" participate in content exchange to reduce downtime and improve experience. A form of insurance, if you want. * I wish scalable video (SVC, or adaptative video bitrate, however you want to call it) was more supported by ffmpeg & container formats. Using a single file for the various qualities would be a natural fit for Webtorrent, as it would allow HQ watchers feed LQ watchers. * Multicast would be a great thing to have on the Internet. Maybe some future/alternative IP stack implementations could bring that back? Yggdrasil is promising, for instance. If nodes could subscribe to a given content, I guess it could be delivered across the network, splitting where it should.
