Streaming audio, video, photos, or slideshows from your iOS device to your Mac is now a lot easier. AirServer 3.0 for Mac (US$7.99) was released yesterday, and gives the popular streaming app Lion and iOS 5 compatibility.
AirServer basically streams anything you can run on your iOS device to your Mac. iTunes video and audio? Check. AirPlay-enabled applications? Yep. Audio and video streaming? Ditto.
