[whatwg] JSON Playlist Format

The use case I'm thinking of is a blogging service that allows a
publisher to upload static files, but they cannot host executable code
like a proxy. They could include a <script> tag as part of their
content and use a third party JSONP
(http://en.wikipedia.org/wiki/JSONP) proxy to load their playlist.

Additionally, in older browsers (IE 6 & 7), I believe that
Access-Control-Allow-Origin headers aren't respected, so you'd never
be able to load XML cross domain, but you can load <script> tags.
