[Public-List] iPhone AIS receiver

[Mike Lehman]

Having spent my working life in the technical field I have always used the 
expression "Technology getting in the way of progress" although there are 
many things we can do today that would not be possible without 
technology...like sending this email for example!

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.
