I've got the exactly the same problem
I have the problem that my media systems are all housed centrally in the house under the stairs with TVs in every room and CAT6A spidering out from the media cabinet. With the Kinect 1.0 I was easily able to build a custom extension cable which consisted of a home made balun (converted USB2.0 to CAT6A and boosted the signal) and 50m of CAT6A.
I can't go tearing apart my Son's Christmas present to develop and extension and after what I have read attempts to cut the cables and reconnect have rendered the Kinect useless.
Therefore I have set up a Kickstarter project (I'll post the link once its been approved) to develop a guide to extending the cable. Hell, if it gets interest I may even extend the kickstarter to producing an extender. Hopefully this will raise enough funds to buy an experimental system that I can tear apart and investigate. For instance we first need to dismantle the Xbox One's Kinect terminal and look at what the data and power is doing. Next we need to try and find a way of boosting the data and protecting against interference over longer distances.
I'll post the Kickstarter once I have it active.
