DRM ala Google

The Guardian: "A greater concern may be over how the content is protected: publishers are fearful that widespread adoption of ebooks could lead to spiraling piracy mirroring that seen in the music business. But Google says in the page about security for Editions that 'once a Google Edition is purchased and is added to a consumer's bookshelf, it can only be accessed when the consumer logs into his or her Google account. When Google Editions are purchased on our site, a Google account is needed to access the content, reducing the likelihood that consumers will share their login information with others'. It adds: 'Each consumer's Google Edition has a unique coding that caches the book when it is accessed through a browser (as opposed to a digital download) ... This means that the Google Edition is broken down into fragments and temporarily stored in – and accessed through – the browser window. The Google Editions web experience, therefore, is not that of a file download – it is an experience that is optimized for reading in the browser. This allows Google to detect and protect against abuse of each Google Edition.'"
