I'm not sure. It seems a reasonable question. I think the obstacle is the browser monopoly. For the same reasons the "semantic web" and RDF knowledge tri-graphs failed in the wild - the current paradigm is frozen in a "works for me" state of arrested development. You could theoretically build this behind the existing "web" but it would get no critical purchase.
