I just purchased the Mac version and got a discount code with the license. It's the best Airplay host I've found on Mac - does audio streaming, video streaming & full device mirroring. They have a PC version and support for non-Apple devices too. http://www.airserver.com
We hope you enjoy AirServer! As a thank you we'd like to give you a $4.0 discount coupon.
Feel free to use it within 14 days on additional licences or give it to your friends or family:
