My tongue-in-cheek response is, "Is it currently in play?" -

In general I agree. However, there is something to be said for a 'Federal' approach to mentorship and network development. In the sense that we live in a global society and often charity begins (and ends) at home in a narrowly focused area of effect. This is positive and negative, the positive is the direct and often immediate impact on people. The negative is the narrowness and resource limitations that come with a local reach.
