As for the outside chance Hollywood wanted to make the story - it could be agreed that the money goes to children of the world, in the spirit of the man who speaks to the children of the world. I don't trust most charities since the majority have 95c in the dollar going to those who run the charities, their cars, their offices, their salaries, their gala events, their friends who own advertising companies, but there must be some that are better for children than others. The idea would be based on the notion that no author benefits financially from it (though you could use it to direct readers to your other works, and to gain visibility in the world), and it is made known that anyone who wants to work on it for tv or movies follows the same altruistic lead - effort without payment. It would be unusual, novel even, and could end up getting publicity based on the 'no lawyers, just morality and the power of public opinion' - so it could grow with more authors, more stories, with fanfic, and publicity, but as soon as someone is known to profit directly from it, they are named and shamed. Legally, it seems a nightmare, but if the concept began with artists creating for arts' sake and all profits to go to children, it could cause enough negative publicity to a profiteer to deter them.
On the one hand, that seems an impossible dream - on the other hand, it could be agreed upon and just see where it goes. If someone tried to profiteer, then media love stories of corruption and 'doing the morally wrong thing'. If authors set up a website to access the stories with the rules of 'no personal profit from these stories, all money goes to XXX' (but readers are encouraged to follow the authors' links to their other works if they like their story) it would be interesting to see where it would go and at what point greed tried to thwart art for arts' sake.
Just rambling, really. Dim lights in a smoky coffee shop in late 19th Century Paris where we gather and talk rapidly in hushed tones about our ideas.
