CyanogenMod 11 Screen Recording APK (beta)

Installation:
adb root
adb remount
adb push Mirror.apk /system/app

Then hold volume up + power. Note: this also records microphone audio :) You can hear the office chatting in the background.

This also has the airplay stuff in it, but I'm still in the process of porting that forward.
