Heh heh...nice way to get my attention.

Anyway, are looking to do the exact same thing, or something like it? If it's the second one and you have the info yourself then I think it's just a matter of setting the "onHover" attribute of a link to call a javascript function to pop up a small window. I don't know if there's an existing mod but you can probably google and find the code to do it, then you just have to put it in a bbcode as the replacement.
