If you suddenly died?

If you suddenly died, such as from accidents (20s - 40s people, which most of we Internet marketers are, don't usually die from foreseeable causes such as dire health), how are your dear websites (income streams) to be handled or transferred to your loved ones? What can be done to ensure that the future website earnings be safely and smoothly made to them after you have passed away and never had the chance to tell them?

I don't currently have a wife nor any children, but I have 2 parents that I love very much. The problem is that the total time they have spent on using a computer is ZERO throughout their lifetime, let alone the Internet. I was just wondering what I can do to make them know how to take on my websites and successfully get the money that will be sent to them month after month, you know, affiliate commissions, adsense earnings, product sales, etc.

Making them never close my banking account will be the first step - but is that possible? I'm not sure if they will let you keep the banking account of someone who's dead. Otherwise, I'd have to outline to my parents the steps needed to change the payment recipient (name, address, bank account number, etc.) somewhere they can find after my death.

This gotta be done cause' money already lying in my bank account is nothing compared to the future potential of my websites which should last at least a few years after no one's caring them until the income stream gradually die out in the end.

Your ideas?
