I am not a lawyer but depending on where you reside there may be a specialized legal trust available to appoint a corporate trustee to manage paying for your domain and website provider. Even better, the trust managers could pay a group to ensure the site stays up and current and ensuring your site is also compatible with all the archiving bots. In most places living trusts are limited to 35 years after you pass but you could probably have that trust transfer to a family members trust. A lawyers that specializes in legal trusts could probably come up with a clever way to do this. All of this said, trust managers are often spread thin and some give minimal effort and this will cost a lot. Or if you really trust a VPS provider, just pre-pay them way too much money and see if you can get a mutually binding contract that is transferable upon death to a family member to keep the site alive. Co-admins. Who do you want to see this site? The whole world, children and grand-children of friends and family? If family just put your site and some videos on multiple copies of thumb drives, DVD's and hope adapters exist or that family members maintain copies.
