FYI, that "half meter cable" is not simple electrical continuity. There are microcontrollers in the ends handling the data as it passes.

I assume the majority of people posting in this thread know this. From a functional point of view, it's still a 30$ half meter cable, and it is also sold as such (not as a transceiver chip/cable kit). It's an interesting technology, though.
