Straight out of Q's lab... Something that snaps around the cable and broadcasts screenshots over bluetooth periodically. Bonus points if it can also couple around the mouse/keyboard cables to capture and possibly? send input.

This falls into the "duh" category. If you think about it, we have been capturing the data stream of HDMI cables ever since they were developed; at the end connector. I'm actually surprised it took this long to decipher the EM radiation surrounding these cables.
