AirPlay is awesome but it could be more awesome if it worked with more iOS apps. TUAW recently discovered that a feature that allowed other apps to use AirPlay was disabled by Apple. But! If you insert one single line of code, AirPlay would work across all apps (like VLC and Safari).
A developer named Zone-MR took TUAW's lead and developed AirVideoEnabler, a hack that's available for download in Cydia (the Jailbreak app store) and brings AirPlay to the awesomeness we all hoped it would be. [9to5mac via TUAW via Engadget]
