The http/www protocol is intended for information you mean to publicize. It allows for subscription-only sites, but its statelessness is not friendly to such abstract notions of who's welcome to look.

If you want to include random public customers and exclude competitors, you'd better figure out how to tell the difference. I surely don't know how to do that offhand, and I don't think it will be easy.
