Good question, if not a little morbid!
Got me thinking too.
If it was a sudden death, there would be no-one who has all my login details to various registrars, host ftp etc.
My 2 business partners do have access to the most important sites though, lock stock and barrel. They would be able to keep those sites running without a hitch. The rest don't matter so much in the scheme of things. I wouldn't be able to put a timeline on how long they could keep the sites going though.
I also funnel all income into a bank account which my wife has access too, so in the short term it would be ok.
Maybe life insurance is a better option
I need to ask your professional opinion on something JD, will try and get hold of you later.
