Dumb question, but where would you leave your will where there's no prying eyes? In a safe?
I think another good way to do this is to have a webserver with a Linux cron job or something that will execute after a set amount of time, i.e. every week. If you don't respond to it, it'll reveal your password to your loved ones via email or a text file. Know what I mean?

Quote: "But seriously, how important is that stuff? Domain names? Music on your computer? Journals? "
Very good question! The reason my music is so important to me is that that is a piece of me that my family can remember me by. I think it would be very unfortunate if, when a painter died, all his art disappeared to never show up again. I'm not saying my music is quality enough to have monetary value, but if it were, it would be important for my family to benefit after my passing.
I know that there's so much more that makes a person than boring old domain names and personal journals. But here's a question, what if, for example, those domain names are earning a modest amount of income? I would definitely want that passed over to my wife/kids etc. Also, if a close family member passed away, I would be very interested in preserving their journal with their permission to show future grandkids as a keepsake. Perhaps I'm too sentimental
