I am a longtime BT Sync user and a new Android TV user as well and I was hoping to be able to use BT Sync to synchronize a folder between my phone and my android tv device. I was able to sideload Sync onto the device, but once it's there, there aren't really ways to get shares onto it. It doesn't have a camera so you can't do QR sync. However, if it could generate QR codes that I could scan with my phone, that would be enough.
