I will keep it in mind, but I also will remember the following:
The neighbors in question are about 50+ years of age (you may think a stern talk with near-seniors about bandwith is a sign I have no heart, but these guys are real jerks). Their kid is a 5th grader with the numeral equivalent of a B- average. What are the chances they can even figure out our 10-character PW, let alone know any software to help them do it? Not high, I imagine.
