If you keep up with the wider electronics world, you know that Apple has introduced a proprietary streaming protocol for its computers and mobile devices called AirPlay. If you're one of the surprisingly large number of people who combines Apple and Android hardware, you'll want to check out Android HIFI, the pet project of an XDA Developers member. The app turns your Android device into an AirPlay receiver, allowing you to play music or standard audio from Mac or iOS hardware.
A new app just hit the Android Market that helps bridge the gap between Google TV and iDevices that use Apple's Airplay technology. The app is called Airtight, and it allows you to stream non-DRM movies and images directly to your GTV. In its current state the app cannot stream DRM content or music, but the developers note that they are working on support for the latter.
The app will only set you back $0.99, so if you have both an iDevice and Google TV, it's definitely worth grabbing.
