Erica Sadun has developed a free (ad supported) 0.01 AirPlayer alpha hack that lets your Mac play host to AirPlay video streamed off of iOS devices. Right, just like an Apple TV and without requiring a Jailbreak. But as long as you're skirting official support anyway, why not install the free AirVideoEnabler app onto your jailbroken iPod touch, iPad, or iPhone to stream video from even more applications than Apple currently allows. Works for us. Everyone else can check the video after the break.
