Publish Book to Website with Disabled Downloading or Printing

[squaredog]

I know Google does it but I cannot find anything telling how they do it. I have a customer who wants to put his book on his website but doesn't want people to be able to download it or to print it. Basically to read it he wants you to be on his website. I looked at DRM but all I have been able to find information about are videos and audio tracks.

I was thinking I could possibly create a flash video from the book but I don't think that is a practical solution. Can anyone provide any more information on this?

Thanks!
