Positioning things in a textarea is at least close to impossible...
thats why I started my project http://code.google.com/p/axedarea/
first place, it is useable to a certain degree, but you yet won't find
you being truely happy with it, as especially on the WYSIWYG quite
some front stuff is missing. As pure Texteditor with a lot of
additional awareness (like size, where each line/letter is positioned,
copy/paste events, keyboard events) it works already quite nice... And
AFAIK it has currently the best online VIM emulation avialable.
