Well, after about ten years' work I reckon I can see all the necessary elements, and more to the point, a way to implement a generic system by bringing them all together.

I first posted here on Ripple getting on for four years ago and I think that a Circular Multilateral Barter (CMB) application of Ripple is key.

What CMB does is to generate - within a community of interest/trust framework agreement - settlement chains of bilateral obligations A>B>C>D>E>A to be 'netted out'.
