Another scary aspect is the coercion of dual (cellular + satellite) units
to operate via cellular connections based on territorial agreement vs.
actual cellular coverage. 

In 1995, I spoke with the then Motorola Iridium project manger and
questioned whether they be might be creating potential safety situations
for users. Some of the Iridium innovators/early adopters are likely to be
sailors. Many recreational sailors have already gotten used to using
cellular vs. VHF for ship-to-shore. Its not too difficult to imagine that
Iridium and its ken will soon replace much of marine HF communications. If
sailors are lulled into thinking that Iridium provides 24/7 global coverage
they could be in for a rude, and perhaps life threatening surprise, when
they find that their dual use phones can't operate with the local cellular
system (no coverage) but \won't satellite with the satellite
(territorially-based contract restrictions).

I tried to raise these issues with the FCC (public safety is usually a hot
button) to no avail.
