Isn't PicKit2 originally deigned for doing that? Ok, the firmware currently
does not support it but the hardware design does. The concept was like to
store 1 hex into it's eeprom and then when you press the button it programs
the target - you just have to supply the voltage through it's mini USB
connector which could be a battery operated PSU.
