I've thought about it and have a plan. I keep an index of all of my snakes: what they are, what hets they have, if they're proven, when they were born, etc along with what a relative fair price on them would be. This way they know exactly what everything is and also so they don't get taken advantage of if they have to sell off my collection.
If something happened, my brother would take care of them until him and my g/f could sell them all off. He has a couple as pets, but no one I know would want to take on my whole collection. So if something happened to me they would be sold off.
