I really doubt it. First, the Constitution places limits on the government; not so much on contractual agreements between private parties. What you and Comcast agree to just has to avoid depriving you of basic human rights (i.e., you can't sell yourself into slavery). Even ignoring that, you give up most constitutional privacy claims if you start disclosing the information to third parties. The ISP is a permanent and necessary third party here. If you tell your ISP that you want to go to ihaveherpes.com or whatever (by asking them to route your traffic there), then I'm not sure you have any claim to privacy as it pertains to a conversation between you and the herpes people. You willingly gave the ISP the information. That's why we need legal protections like the prior FCC rules. Because by necessity, you need something above any bare constitutional protection.
