In the context of DTube IPFS is simply storage for video files, where the metadata + interactions are on the SteemIt block chain. It's cool that the author has generalized the concept onto pure IPFS. It may work better than my experience, which used IPFS to store very large contiguous mp4 video files (eg. 15min 720p max). IPFS is nifty but I'm not convinced of its ability to support an intergalactic workload quite yet. I've looked at it vs. CDN for a video delivery platform and have a much more robust system built on primitives DNS -> CDN -> HTTP -> HLS segmented MP4 + static HTML site w/ SPA chunks in just a few weeks. I explored similar ideas with using encoded public keys, hashing, and side-channel crypto key distribution to support some interesting workloads. This is cool because it's a no-voodoo solution, just HTML and RSS and JS and chunked video files, and the CDN handles the details invisibly. With IPFS on DTube I've only been able to author a little data before running into queuing blocks where I was unable to continue adding content. I have some videos on my YouTube channel talking about IPFS and giving demos in the past 1-2mo, 'iSpooge Daily'.
