if your site has a valid copyright statement about the use of the data then probably the only thing you could do against such a stubborn pirate is to begin legal action. Even Peter's graphical option won't be much use if they hire someone to sit there and manually scrape the data, which they may well do if they're half as determined as they sound. Some legal action and bad publicity can do wonders to prevent this sort of thing, as we've discovered before. The flash thing *is* an option (but which again, won't stop someone manually writing out all the data). But do you a) want your customers to have to use flash as an interface and b) want to go through all the hassle of creating the flash interface with the looming dangers that the flash plugin might be facing at the moment in browsers.
