Programmable routing of VCC and GND (up to 500mA)
You could use two pieces 20x3 2.54mm pitch headers (120 pins total but only two parts to stuff) and one shunt for each power pin. Samtek ones are in stock at Mouser. Just run the GND and Vdd along the outside connections and link each center pin to a pin on the ZIF.
But I think I like @DkNguyen's daughterboard approach better. Less likely to fry a chip, for one thing.
