I'll take the first crack at this.
I think it would have to be a long-term vision and policy that would span more than one politician's term in office, to be blunt about it, because it just can't be accomplished in that timeframe. Ashley referred to an average of ten years from idea to build, and that's a pretty reasonable assumption.
So it would have to be a long-term vision, but it has to be supported by a continued long-term financing policy that is sustainable, and not by a budget every year that may or may not support it and can be changed from time to time. It has to be something that's basically in concrete for the next 20 years, and every year a significant amount of money has to be put towards building this network. It will not happen overnight. It will be done over several phases. It's a difficult policy to put together and also to get passed by all the people who need to participate.
