Does anyone know if Amazon or Google are somehow obfuscating or DRMing their casting protocols to these devices? If anyone ever made an unofficial 3rd party stick that supported both Amazon Prime plus all of the services already supported on Chromecast I'd buy one for every TV in a heartbeat. Until then I'll probably stick to Rokus.
