I am not quite sure if this is even possible, but I am sure you would have better luck in the cPanel forums Might be able to tweak something up with mod_rewrite.
In any event.. Good Luck
I think fire100 is right, that's where the header files are located. Unless he doesn't have root access, then his host woul dhave to have mod_layout and then he could do it by putting a .htaccess in each account where the banner would show up. But people could delete the file, so its best to do it with a VPS or dedicated server, when you have full root access.
