[Public-List] iPhone AIS receiver

[Michael Grosh]

Commercial vessels are not allowed clearance into N.Y. unless they have a
functional AIS. That reality is what drove the original stampede to AIS.
What I find disconcerting from the technophobe viewpoint is: like the
promise of computers in every office was supposed to make life easier for
workers, all these electronic marvels do is raise the intensity of
movement, or work, or whatever. Yes productivity, and big brother certainly
benefit, but easier, not so much.
