Maybe this service already exists... A web service with VPN interface that instantiates a from-scratch account on log in and then deletes it when you log off. Do all your browsing this way. If you actually want to buy something, your credit card information stays with the service as a middle-man and it makes the payment via it's own banking interface and keeps a small fee for protecting your privacy. Many facets not contemplated in that paragraph, but maybe you get the general idea. Is there such a service yet? 'Anonymous' access to the Internet and still have the useful bits available?
