The issue isn't the ads, it's the harvesting of clickstream data and a cookie isn't cutting it. Multiple HTTP clients across multiple computers makes for a hell of an opt-out procedure. I looked at the webwise opt-out page and it uses javascript to set the cookie, that's neither guaranteed to be enabled or even supported (netsurf, dillo, lynx etc..) and there's issues for other client software like wget and curl.

Since techteam/phorm claim this is network level technology, why is the opt-out not handled per subscriber at the network level by the ISP?
