Perhaps the requirements for a Class 2 source will reduce the size of this loophole. Note that 6V x 8A = 48W. Not enough to charge a battery and run a multi-core processor; but probably more than enough for a 'netbook'.
So the bean counters will have determine if the extra cost of construction/materials for a non-limited source (Class I, >100VA, >8A) will still be better than buying a smart and efficient power supply.
