Yeah I saw that and I tried it out as well, my experience was it was pretty high latency. My understanding is they were shoehorning HLS into BitTorrent so latency is governed by the longest segment length. Unfortunately there's a tradeoff if the segment length is too short then BitTorrent starts not behaving well and if it's too long then HLS will increase in latency. It's really cool tech though and especially doing it back before WebRTC was really a thing was an achievement.

My goal for the CDN is to make it lower latency that it could be used for video conferencing. In practice I have more of a one-to-million distribution in mind but it's a cool puzzle.

If you're interested, I'd love to talk more! I'm in NYC if you happen to be too, I love meeting people interested in live video :)
