It's probably possible in most jurisdictions to implement voluntarily by holding the copyright with an incorporated cooperative or partnership, of which the original authors are the owners. Corporate bylaws would determine licensing, allocation of the revenue, transfer and other such questions. Some jurisdictions do not allow either waivable or transferable moral rights, which could make this either complicated or infeasible. In some jurisdictions, the copyright law has a mechanism for professional associations to be responsible for collecting the copyright within a certain area. Now that I think about it, the model seems like it might be adaptable to software. https://en.wikipedia.org/wiki/Copyright_collective https://en.wikipedia.org/wiki/Copyright_collective
