An avid Mac developer has released an Apple TV plug-in SDK (Software Development Kit) titled BackRow Developers' Kit. The project includes the headers for BackRow framework, iPhotoAccess framework, and QuartzComposer frameworks -- all of which are required to run appliance plug-ins as well as the BackRow Test application. A project template for Xcode provides everything necessary to start a custom appliance plug-in, creating the Info-plist with the required elements as well as Appliance and ApplianceController classes with links in the appropriate frameworks. The SDK is available for download, and several BackRow programming tutorials are posted on the developer's website.
