If I look at the survey results on barriers to e-commerce adoption, regulatory barriers are not identified at all. The main element that is identified is the inappropriateness of their product or services being sold online, which is interesting because, in some cases, it is true. In other cases, it is just that they don't understand the opportunities that e-commerce could offer. It's more of a strategic discussion as opposed to a regulatory one.
