I'm gratified to realize, going by remarks made and bits of email I continue to receive, that the number at the end of My kingdom for that key served its purpose to a "p".
Thus: for you "very smart" guys out there, good on you! My mistake, the last digit on that number should actually have been "5". Run with that and let's talk again in another few weeks.
For you more normal souls, please freely share my gratification.
