It's philosophically hard to decide how important each contribution is, and all the obvious ways of trying to measure it are [emphasis] obviously [/emphasis] wrong in some cases, they're obviously closing their eyes to some important part of the facts so I think that this kind of solution is probably not feasible when everybody is free to publish modified versions. But for those kinds of works where it is not crucial to have the freedom to publish modified versions then this solution can be applied very simply once we have the convenient internet payment system to base it on.
