Chasing up some BT Webwise javascript mentioned over on BadPhorm
http://www.webwise.bt.com/includes/c...ise/webwise.js
It seems that the cookies DO contain an ISP identifier.
I then had a look at the video on Webwise.com - it carries the same linking graphic as in the js file above
Interestingly - that vidoe only contains logos from BT and TalkTalk like the rest of the Webwise.com site.
If that is the video that BT are planning to show us to inform us about Webwise then it leaves a lot to be desired in terms of being a comprehensive description of Webwise, to comply with the Consumer Protection from Unfair Trading Regulations 2008.
