Default [Q] Screen mirroring tool for PC - BBQDroid?

Hi there
I'm looking for tool that mirrors the android tablet screen on a PC as I would like to use it to demo the app that is developed. Could you point me in right direction? I wonder how did the guys at Google I/O 2014 got so great smoothness when screen sharing on their N5 devices?

I don't want to use TeamViewer as I find it too slow -- preferable the frame rate should be 15 or more FPS.
I've found BBQScreen DEMO in Google Play (can't provide direct link due to anti spam rules) that looks promising but apparently their website is down for coupe of days. Maybe someone has the installation package for windows client?
