i know there is a lot of controversy surrounding things like diggbars and the stumbleupon toolbar, but i'm just trying to figure out how this is done for research.

i am guessing you start out by making one html page that is your topbar frame, and then on your actual page, you build a function that you call in all your links. the function would do something like place the topbar on top of your outgoing link - like cnn.com or whatever. anyone done something like this before?
