Except for continuous editing or live visibility of edits in progress, that's a lot like a wiki with wysiwyg editing. http://www.mediawiki.org/wiki/Extension:WYSIWYG

You could probably extend wikis like mediawiki to have live visibility of edits, at the cost of performance. Separate db or redis storage for in-progress edits, and query that before retrieving the last static version of the page...
