The whole premise of this seems wrong. I've worked on large financial systems that have happily supported different rules for different countries using a relational database. The database was never the issue, it was how to handle testing and feature enablement. This seems like the wrong cure to the problem, and a cure that will end up causing more problems than it solves. i.e. a hack. I'd love to hear more about the rational. I just don't understand it.
