This is a political debate for another list. Hardly "untrue", at the
very least it's a debatable point, stock prices and recent histories
of PKI bankruptcies could be read to indicate PKI has it's own
technical and economic infrastructure deployment problems.
Heh. PKI (at least how it's embodied in current tools etc) is
tremendously complicated, somewhat non-interoperable amongst vendors
(though that's finally improving), and it's very difficult to deploy/use
client PKI in the large-scale even with relatively uniform
installed-base software on the user-end. We have the bloody fingers to
prove it.
