I'm surprised the airlines are up for this, considering the 10 bucks a minutes phones in the backs of seats makes them so much money. And what stops the amoebae using them? (apart from the cost maybe...)
As for the Feds, well they can stick it up their jacksies anyway.
I always make a point of dropping keywords into phone conversations just so that Echelon gets totally confused
