Hi Glen, > I suspect the "orderability" only requires partial orders rather than > total orders.
yes, but relativity implies locality - that means all causes for A and all effects of A would have to be in the past/future light cone. So for the causality at point A you would have total ordering. If things out of the light cone are not comparable - who cares? - they don't affect A anyway.
