Testing content editing with Sway
It's not a perfect tool, but an excellent example of how editing content and merging streams of media from different sources could be done in the future with Content Management Systems.
The collaborative features of Google Docs, Sway and others have already set expectations on working with content in a shared virtual space. Heavily integrated services and others will continue to be custom work, but for many uses this kind of self services will be more than enough.
