thanks for the link! the cost is huge compared to magshoe--100-170k vs maghoe's 5k also political issue with sending body pics at the smaller commercial airports I dont think the cost will be justified I think people are mostly ignoring the non-airport market for magshoes, which is huge IDOI's CEO stated that about 1.4 MILLION walk-through metal detectors are deployed world-wide each one is perfect candidate for magshoe taking even 1% of the 1.4 mil is 14,000 x 5k each is 70 MIL !!! thats hyperthetical sales at abt 1% of the install base imho of course :-)
