Thanks guys... So to reiterate... Both methods are acceptable according to the NEC? That is.. Breaking the Neutral or not...?
That's really the back bone of my questions... the other thing was a tangent... but then I digress... again...lol
I'm aware that the BEST method is to use a UL approved transfer switch... But I'm still in question as to who has the better homemade system (remember my neighbor and I are both qualified electricians and we keep an eye on our unorthodox contraptions...) He with the backfed breaker... or myself with the elaborate ( and fail-safe , if I may add.....) cord and plug system...Easy on the flames... neither of us would approve a customer getting such a setup...but I do want to know what you think.

Sparky, Unless there is some kind of mechanical interconnect between the main breaker and the back fed breaker at your neighbor's house, his installation is in violation of 702-6. If there is an interlock then both systems are OK, except that the grounded conductor to the generator frame must be removed in his and must be inplace in yours. You must also have a grounding electrode system connected to the grounded conductor at your generator. Don(resqcapt19)
Of the two, I would sleep better with your arrangement. His is a lot simpler, but more prone to accidents. It is potentially a very dangerous situation. I probably don't have to elaborate on ther dangers if the main was left on or there was some leakage through the main back to the pole.
Does anyone know what would happen to the generator if it was hooked up, breaker was turned on and utility power was also present?
