If you feel that a simple ascii-text tooltip will do as well, you could
try this (Distiller/AcroPro _not_ required):

    % arg #1: text to put on the page
    % arg #2: tooltip text
        /TU (#2)/T (tooltip \thetooltip)
        /FT/Btn/Ff 65536/H/N


PS (to Juergen):

So far, I haven't managed to make parts of the page content optional using pdfmarks and Ghostscript.
