For my Visual Studio Live! talk on Windows Azure Mobile Services, I decided to go beyond the "todolist" quick start samples and implement an application that illustrates more framework-specific and platform-specific features. The application is called "Rent a Home", and helps users share apartments for rent and view apartments for rent on a map around their location. Although this is not a production quality application -- for one thing, there is no way to contact the apartment owner! -- it's a more realistic illustration of why you would want a shared backend for your mobile application on all four major mobile platforms: Android, iOS, Windows Phone, and Windows 8.
