I have many ideas along these lines, perhaps something under the auspices of the United Nations, but it couldn't be open to every nation to be involved in, only those that had made a recognizable effort to be a space-faring nation. Minimum being hacing launched a rocket into space. How one would deal with the ESA then is a good question, because they should probably all be on board, but the representation would be fairly widespread. I need to ponder this further, but i do agree, this could be a stand alone topic, perhaps integrated with the Commercialisation of Space, the two go hand-in-glove.
