Very nice! I was seriosuly missing something like this, especially for my org-files. A few times a week I want to add or change something to my todo.org but I can't because I'm at some corporate computer. At the moment I try to remember and make my changes when I can, far from ideal.

My plan is to use parenscript to convert the org elisp code to Javascript and provide some extra functionality such as document export through a webserver running headless emacs. Any opinions on this idea? Could this be possible with YMacs?
