I did watch the video, but used poor semantics. :-(
Fair enough that it is multiple observer context and I didn't spell it out. It's essentially locking in an OT consistency model/control algo. I'll give you that sync is a really hard problem, but Etherpad, Wave, Google Docs, etc. are just a few examples of some off the shelf solutions (the Wikipedia page details more and doesn't even cover the whole set of what is out there, particularly if you consider version control systems). The big commercial success for generic document sync was probably Lotus Notes, and they made the sync solution a separate product product.
Again, not knocking the product, it looks like a quality solution and one I might even recommend, but I'm not sure I grok how one sees this as opening up a new set of possibilities.
