Interesting concept -- It seems like it might work better as a browser plug-in though.

If you want to keep it as a web site, I would make the interface (your search box, browser list, etc.) as unobtrusive as possible (remove all the daed space, try to move your entire search interface to a bar at the top or left perhaps, and create a results pane who's vertical scroll bar is flush w the right side of the screen -- this will create a much more comfortable and familiar experience for users.
