or perhaps, that building tools that actually solve these problems
as opposed to chipping away at the edges is (a) fundamentally difficult
(b) requires many kinds of expertise, most of them scarce, (c) has
been frustrated by governments and patent holders who were bent
on trying to control things, and (d) has not kept pace with the
development of the 'net.
OK, I'll call it quits now, before we begin to explore who has
contributed to addressing these problems in any visible fashion, and
what the relative levels of security expertise are among the folks
sending these messages.
