Ebook Library with Unity3D?

Hello experts,

Unity3d is my go to tool specially when it comes to targeting different platforms, and lately with new UI (4.6 and later), even practical for non-game apps such as interactive books, quiz like games .. etc

I have to develop a Library/book store where Native development is recommended by many, and want to know if anyone developed such an application using unity3d with backend development included.

Any links, references or advice is appreciated.

The app will have a filtering screen where to filter age range, and some categories to filter from, after criteria is set, user will press search and a list will be displayed.

Selected book will be downloaded at runtime. Data will be retrieved from an online database.. no more details required here at this stage i guess.

Please share with me any advantages/disadvantages with any additional third party suggestion to use.

Thank You, Vasken
