They could have two offereings, 1-way for simple control and 2-way for feedback (such as Crestron does now). It could also be a future add-on...an RF reciever that plugs into the existing USB port, which already is capable of recieving data. I guess power could be an issue though...anyway just a thought, as I'd love nothing more than to see my entire MP3 library listed on my MX3000.
