There is more than 1 "flavour" of Videoguard, probably 3 - possibly more, and you have probably found the Videoguard CAM that is for the Scandinavian countries.
We would all like a Videoguard CAM for the UK (at a reasonable price of course) but I don't think it'll happen without government pressure - and we all know how likely it is that Tony Blair would try to face down Rupert Murdoch.
