Interesting questions to which I don't know the answers.
In regards to profit, perhaps if such an organisation could raise money in some way other than levying charges on clubs (thereby remaining independant)... Since one wants a governing body to be independant otherwise theres no point in having one, but if it is democratic then by definition it is not independant.
And I am now way out of my depth...
I find the topic interesting though, I'd love to know what you would do if the task of forming a federation fell upon your shoulders?
