Any high voltage DC distribution system would require every load to have a single run, with intelligent connectors paired with remote switches to shut off the circuit at detection of any detected alteration of the circuit (eg. Ground fault, capacitance change, etc.) High voltage DC is spectacularly more dangerous than high voltage AC.

Could you give more details of this danger?

  An arc on AC is more likely to be extinguished since the current drops to zero many times every second (so eg, on 50 Hz AC, an arc is not likely to last more than 1/100 of a second). DC switches and circuit breakers are designed with greater concern for arcs.
