If it's a big deal change DNS servers. Or use software like Tor to hide your location and browsing habits. The information they get from you would be useless and couldn't be targeted back to you because they couldn't trace you.
Tor is definitely a good idea, but the problem still exists that all of your traffic is going through the NebuAd box. Keep that in mind..while they say they do not look at any traffic other than port 80, it ALL goes through that box. Do you really want to trust a company who has execs who used to work for the Gator Advertising Information Network? In addition to all of the traffic passing through that box, any web forms that you fill out that are submitted would over port 80, which they do admit to monitoring. If any of those had personal information in them.... well you get the idea.
