        I started to write a technical critique of this idea, focusing
on the security implications of distributed watchlists, the costs of
building such a monitoring infrastructure, the various and sundry ways
to avoid it.  However, I think there is a more fundamental issue here,
which is that the events of 9/11 were done in a very low tech way that
all the machine surveillance and message grepping would not have
caught.

        We Americans really like technology as a solution, and here we
see an interesting technical solution proposed, so we start taking it
apart, and asking 'could you do this?'  I think the answer is yes,
with enough money, we could build something that would be far less
effective than a few hundred agents infiltrated, subverted, or turned
to our side, reporting to us on planned attacks, making mistakes, and
otherwise creating chaos within the opposition.

        Why isn't the FBI taking that money, and using it to train
agents to speak Arabic, Pushan, and Farsi?

For the avoidance of doubt, I sholud have been clearer: British law no
longer requires (as of July 2000) warrants to be served on ISPs if the
interception can be done without them.
