It would be fantastic if there were a stand-alone sensor, that could connect via bluetooth or even USB via adapters. People could order it separately. I realize that not all phones / headset combinations may allow a bracket, but the level of most viewers now, it wouldn't be any worse if it was just a velcro patch
Also, this would give a way for software developers to work with it. You could even call the stand alone module the "DEV Kit" and I'm sure a ton of enthusiasts would buy it.
