This is a difficult problem in Europe and fair play if you can get it done. I have some friends who built the software behind Sentenial which does DD processing in Ireland & Europe. Their CEO & CTO was scared away from adding in CC processing into the mix because of all the complexity. Not that this should necessarily scare you, just go into this with your eyes wide open. If nothing else, this is a bureaucratic minefield.
