I just found this new tool (writing a newspost about it at the moment). If you visit this URL: http://protu.be/xklzt/screen/ you can use your phone to scan the QR code which allows you to send music to that screen.
So this way we can make our public MyCE music video hangout
If you'd like to try it out then head over to: http://protu.be/xklzt/screen/
I've never used QR/NFC. Galaxy Note 10.1 was announced yesterday, but its display has less pixels... I had too much coffee and too little sleep today.
