 Considering that you'd have to be as close as possible to 100% compatible with
the current webbrowsers out there (or there'll be hacks to get around the
filter), you probably would have to use a webbrowser to render the page, and
then use OCR to compare the resulting image/page with the source (to find if
there's hidden text, and probably using the source to improve the OCRs
accuracy).

 But, of course, that you could get around simply by using javascript to set
the webpage to the size of the screen and then use a :hover on the main bodytag
to show/hide material.


And people wonder why I block HTML-emails from most of my emailaccounts... =/
