What an incredible idea. This is what we need as a generation to come up with innovative propositions like this. I like your thinking about fairness and equality between miners/seeders, this is something that would promote stability earlier on which is very good thing. Few issues come to mind about the nodes, but I will talk about this at a later date, i.e. once I get some sleep.

Overall, this seems very solid, Sprout is a refreshing name and I look forward to more discussion.
