Many thanks for Alexander for your great paper on the 2006/7 trials. I am about a third of the way through it, but it looks good so far.

In para 3.1.3 you say "In the case of the secret trials carried by BT PLC in 2006 and 2007 Deep Packet Inspection went one step further in that it altered the contents of the network stream. In order to test the effectiveness of the targeted advertising system (OIX), software source code called Java Script was injected into the network stream to alter the webpage the end user was delivered on their screen, in order to display
advertising banners which had not been placed there by the content owner and download a cookie file onto the end user's computer.[15]"

In the case of the 2006 trial there is indeed evidence that javascript was added to webpages. However the 2007 BT trials appeared to use a different implementation and when I was 'trialled' at that time I am pretty sure there was never any javascript added to the pages I browsed. In particular when I found my own website accessed via sysip.net which raised my concerns I deliberately looked at the source which came back to me and it was exactly the same as my original. I also do not recall any suspicious cookies from sysip.net or elsewhere arriving on my computer either (I look through my cookies regularly and would have certainly noticed them). So I suspect they were just checking the 307 redirection process in those trials.

Will let you know if I notice any other errors (tomorrow now, about to go out).
