"Editing" user text on the fly?

Question

I would like to implements something like vBullettin (or stackoverflow) does. When the user clicks "edit" the HTML text is converted to plain text into a <textarea></textarea> ready for the editing.

How would you implemeent something like that? Note I can use jQuery.

I would like especially know the authentication part (if users clicks "edit" on soemone else comments there is a warning)

Thanks
