I'm currently working on something just like this. https://www.mynexus.io https://www.mynexus.io (It's 95% ready but still a WIP, so excuse any clunkiness and the lack of content) It's a content aggregator for content creators (plus custom postings) -- Make your YouTube channel, Vimeo Vids, Twitch streams, etc. available to your audience all in one spot.* My hopes is that once this catches on, it will become easier for new video hosting services, etc. to pop up since the huge current barrier to entry--providing an audience for content creators--is no longer a necessity. The only thing new services need to compete on it the value they contribute as a content host. This isn't quite as technical a solution as what you described, but the current problem is that of coupling content hosting and audiences, and I believe severing that connection will bring about many improvements to online content creation and distribution. Feel free to respond with any questions or email me (yaniv <at> mynexus <dot> io). *The list was about to include Mixer too, but that opportunity faded away, unfortunately. Will be adding more content sources over time as they are requested by creators.
