Continuity/USB

I have seen lots of posts on needing Bluetooth 4.0 lte and wifi ac for a lot of continuity features, and I should be good to go after upgrading my cMP. I haven't heard anyone mention this, maybe they already have it or are working on it, but I think they should add this functionality if the devices are connected through USB. I think it would let everyone use the features, and knowing how they work might be enough for some to want to upgrade to loose the wires.
