The only way I can think of is to write in Flash. However, you have to remember, that if you write so that the scraping tools cannot see your HTML – then neither can the search engines.
Likely, you would drop right out of the SERPS entirely doing something like that 
All code engines are there to supply browsers with HTML compatible code. If they do not, then nothing is viewable. If they DO supply it correctly, then a scraper can scrape.
Hope I made that sound right.
