If I don't forget...
BTW - the tool was written in Obj-C and I don't know if
it is better than /most/ PCB programs. It is only better
than /all we have reasonable access to/.

That shouldn't be too difficult. We can simply switch
off VAUX4 and WiFi and BT don't eat any power...

The Chip is said to have approx. this spec:

WiFi operation
	160 ... 250 mA (continuous receive @ 11 MBit/s
			        ... continuous transmit @54Mbit/s)

802.11 Power Save Mode
	10 mA (I don't know when this mode
	becomes enabled by the drivers, if at all)

BT operation
	28 ... 55 mA

BT Deep Sleep
	2 mA

Power Down
	0 mA
