The way I see Shadow DOM is that it's an environment for an encapsulated web component or embedded app to run within. Most frameworks can be mounted to the DOM at a single spot, so should be pretty compatible, I would think. There are also a lot of existing web components libraries that have been developed in anticipation of first class support for Shadow DOM in all browsers.
