Can someone implement this in-post-comment system as a plugin ?

Hi friends.
Here is a great implementation of the old YahooUI allowing you to get comments that are intended for a specific area of the post.
an example and explanation how to do it, we can find here (!) :

Any one wants to implement it in his theme, or make a plugin out of it ?

Tal.
