The reason for this is all traffic for the entire exchange will be passed through the Layer 7 technology during the trial and then redirected as described by Dr Richard Clayton to a "special machine" masquerading as the web site you want to access. This is the main consequence of the cookie system they are currently using.

If you note the correspondence R Jones had with BT (above) you can see it states any user who is "invited" to the trials, not any user who "accepts" an invite. When you read that statement and understand the technical analysis by Richard it is clear that this will include everyone in the exchange as it specifically needs to go to the webwise domain to get the opt-out cookie. If you redirect to localhost that cookie will never be set and you will be stuck in a loop. The loop that Kent stated could only ever effect a maximum of 1% of customers...

I made bold the part I wished to check up on it should be impossible to do the whole exchange since there will be some on the exchange that are not BT BB customers so not part of their network to trial this on...
