One of the exciting new features in iOS 4.3 is the universal enhancement made to AirPlay. AirPlay existed in iOS 4.2, but it was limited to native iPhone apps. With Apple's new 4.3 firmware, developers are given access to AirPlay functionality, allowing them to incorporate it into their 3rd party apps.
AirPlay is not just limited to App Store developers either; authors of web-based applications for the iPhone will now be able to stream video to the end user's Apple TV. App makers have been pleading with Apple for access to AirPlay APIs (Application Programming Interface) since the feature was introduced in iOS 4.2. But what makes AirPlay so exciting for develepors?
