IMO, decentralized network technologies are becoming more important, as we now have renewed impetus from government/corporate bullies seeking to censor the internet 
Back in 2011 (or 2012? I forget) we tried doing releases with trackerless torrents and found that they essentially didn't work. The trackerless stuff works well enough to make DOS attacking trackers somewhat ineffective for extremely popular torrents, but for niche torrents they mostly didn't work at all (partially due to the background DDOS level against the bittorrent DHT stuff). I don't think anything has changed regarding this.
