The problem with only fiber and no satellite is rural areas (and some
not-so-rural).  Until the 'phone companies completely "rewire" *all* lines with
fiber, there will be many areas with no high-speed connections except by
satellite; latency,  prop. delay, tapping issues aside (we won't even talk about
problems where they effectively "crash and burn" - a bit hard to send someone with
a bucket truck to take a look!).  And, I agree completely that "secure/untappable"
is an oxymoron.

 The issue of "rewiring" is both financial, technical, and regulatory.  Financial
in that there is a huge investment that must first must be written down be it
'phone lines or cable TV. Technical; there are still many pieces of hardware that
have not yet been designed or are expensive/primitive - e.g., check out the price
of an optical modem.  What is needed are small "taps" that can be placed on the
optical waveguide line to provide bidirectional communications; these could be all
optical or a small "modem" powered by the coax from the house - at some point (for
the forseeable future) one must eventually convet the optical information to
electrical.  It is still tough to make high-effeciency lasers (at the correct
wavelengths) and how channelization may occur is not yet completely clear.
Regulatory: there is a serious fight among the 'phone companies, cable companies,
and satellite providers for the market - all will lobby (kind choice of word here)
the policy makers (all countries) to the hilt.  Of course, the present turndown in
telecom doesn't help a bit and delays are certain.  As one involved in the
photonics business (R&D level) I (and mny of my peers) still find it unbelievable
that people being paid huge $$$$$$$$ could not see when the balloon was going to
