I really like the notion of Matt Andrews' [isomorphic-fetch](https://github.com/matthew-andrews/isomorphic-fetch): it bridges the API gap between client-side and server-side http requests, so developers have less to worry about.
But I think the term [isomorphic](http://isomorphic.net/) is generally misleading: it gives developers a false impression that their javascript code will happily run on both controlled server environment as well as uncontrollable user browsers. When the latter is only true for a subset of modern browsers, not to mention browser quirks.
Plus if you are going all the way to implement `XMLHttpRequest` in node and then promisify it, why not go from node's `http` to `fetch` API directly? Your browserify build are going to be vastly different from node anyway.
