Actually even the 2706/7 can run fine without the actual +5 volt wire on the cable in most circumstances.

You HAVE to have the ground wire though. You still need a voltage reference (ie ground) for the differential pair. As I said before putting chokes etc in line with the ground is a bad thing to do as well. Some designs do that to try and meet EMI specs, but all it can do is mess up the quality of the data transmission.
