I am posting on this old thread since new technologies appeared during these years that support web scanning feature.
You can use LEADTOOLS HTML5 Twain scanning technology which gives the developer the ability to control any TWAIN-enabled device from with HTML/JavaScript web applications.
You can start by reading the following white paper to get more information about LEADTOOLS Web Scanning feature:

Also, you can check the online web Scanning application here:
