"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
"...That is why I'm optimistic about tru2way. It opens the door for other equipment manufacturers who do not have the conflict of interest of also being content providers."
Except it doesn't. Tru2way devices are forced to run software provided by the cable company, and all Tru2way devices on a system will run the same software. You will be just as screwed whether you use a regular cable box or a Tru2way device.
