For data as plain text, one could imagine to have an editor based on Markdown. I’ve seen shareJS used this way. IMHO once one wants more sophisticated formatting options this is not as user-friendly as a WYSIWIG solution.
Alternatively, the HTML needs to be converted client-side on the fly to something like JSONML http://www.jsonml.org/ Would that be feasible from a performance perspective?
