This here puppy's (Mirage) supposed to do the trick - see their blurb below. Of course, your visitors have to get the client for this to work. The technology sounds logical but the price? Well, if you have to ask... Adobe supposedly has something similar in the new versions of Acrobat which allow you to created protected PDF files that prevent copying their content. "When an application (e.g., a Web Browser) receives a Mirage protected document, it renders it still encrypted to the screen. Mirage Client monitors data being written to the screen, and decrypts the protected data en route to the video memory only. As the data is only in the clear on the screen, all unauthorized attempts to copy, forward, save or print a document will capture the encrypted data from the RAM only. Similarly, Mirage Client uses patented technology to ensure that all attempts to screen capture the decrypted data from the video memory fail (whether using the Print Screen button or 3rd-party screen scrapers)."
