I really like the idea, but the time frame of when the protocol will be "complete" seems (as noted by other commenters here and by the fact that it looks to have been posted in 2013) a bit sketchy. Still, I'm seriously thinking about making server / client libraries for myself and others so this is less of "Here's this really cool idea and a few sort-of complete implementations", and more "Here's this really cool idea, and here's how you can integrate it into your sites if you want".
