Editing Org-mode syntax in a web-browser (textarea)?

[Thorsten Jolitz <tjolitz@gmail.com>]

Hi List, 

this question is explicitly *not* about popping up an emacsclient
instance from firefox or chrome to edit an html textarea in Emacs. And
its *not* about emacs-w3m or eww. 

I'm rather interested if there is something like Ymacs
(http://www.ymacs.org/)

that supports Org syntax too? 

I saw Org-mode mentioned in the context of Codemirror, but its not in
its language list (http://codemirror.net/mode/index.html). 

Both of these browser editors are of course extensible, and since they
support markdown, maybe creating an extension for org-mode would not be
so hard, but I would like to know if there already exist some useful browser
editing tools for Org syntax out there?
