I don't have anyone lined up to deal with Stuff, and I don't think I've got any Stuff that would break my folks' hearts (more than they'd be broken by the fact that I'd just died), so I'm not that concerned about the local-person issue; except that the password matter would probably have to be local, for my own purposes. I can't have someone knowing my passwords if I'm still using them - but writing them down and putting them in a drawer, or some digital equivalent, could be a solution.
