"faster" in conjunction with the orlanda effort and some of the
predictions on possibly 40mil (most frequently travelling) people sign
up if such programs were rolled out around the country.
the issue raised was that they were effectively paying to have a
priority queue for the existing screening stations (effectively could
take the place of the first class queue at some airports) ... and what
is the characteristic of a priority queue if nearly everybody is
standing in the priority queue rather than the regular queue.

the order of service ... priority queues have the appearance of meeting
their objectives when only a small percentage of the total population is
in the priority queue.
