I'm inclined to say that semi-active is easier because "all" it needs is
for the ISP to employ some policy-based routing (assuming there is such
a thing) to funnel a small proportion of its traffic past the
interception spot. 

The passive system requires you either to find such a point *without*
the added help of the policy-based routing (difficult in a backbone-less
architecture), or to find enough different places to put a succession of
of boxes to have a similar enough effect.
