Technically trivial, ethically horrible, especially if it's not disclosed to the user. Personally I'd rather format my text on a notepad and copy/paste it to the chat than let others spy on me like that and even then only if I was forced to use it. Which, fortunately, I'm not. This is one of the reasons I use NoScript.
