Boingboing the popular blog posted a short unfavorable note about
Magicjack and their phenomenally anti-consumer terms of service in
April 2008. Magicjack sued, and it was just resolved. Magicjack
comes across looking, to put it mildly, like a bunch of pompous
spoiled brats.
Boingboing's just published their version of ths story. I looked at
some of the legal documents they linked to, and they confirm what it
says here:

My two cents:
Back in the eighties when I was station with the US Army on Okinawa,
Japan we had a microwave link to the Naha harbor where are biggest
issue was tides. A ship would be loading/unloading and when the tide
came in would block the path. So if you were on duty you'd want to
check both the tide chart as well as the harbor schedule.

The other little gem is reflections off the sea.
Get the beam path wrong and you get destructive interference at some
point in the tide...

I think someone less than the government, but with a good skill set,
would go for the "person of interest" NID. Some good inductive
coupling and a state-of-the-air transmitter would seem to fill that
bill.

The problem is not making a connection to listen in, the problem is
that the volume of conversations (or e-mail, or usnet posts, etc) is
so great on fiber (or microwave, for that matter) that considerable
computational resources are needed to separate the wheat from the
chaf. In the "good old" days, the tap would be made on the loop, so
there was no need to try to extract the "right" circuit. Today with
cell phones and call forwarding and all that technology, picking out
the "right" circuit is problematic. Of course there is a law that
allows law enforcement to access a single individual, but if one is
looking for an "unknown" individual, the problem is much more complex.
In short, if you know what line to tap, it's easy. If, however, you
are looking for "suspicious" activity, the problem is much more
complex, probably beyond the ability of less than a government.
Just my two cents...

Also use AdblockPlus, all of these things really clean up annoying web

If you are worried about snooping then encrypt the link?

But subsea fibre cables break as well.
And, repairing them is usually a 1 to 3 week exercise involving a
maintenance contract and a cable ship.......
Lots of islands seem to have microwave originally acting as backup to
subsea fibre - or multiple fibres on different routes.
It tends to cost real money though....
