for my home and to address the privacy concerns have written a script which deletes my history automatically, I don't have to personally log in to do it. In any event, I don't care if OpenDNS knows I made a lookup request for any of the sites I visit. If I really want to cover my tracks, I would not use it. However that said, I would never, ever, recommend this service for an enterprise.
Care to share this script?
