At first glance, it seems sheer idiocy to use an open

of-life-and-death public infrastructure like power
systems. What do you think?
I think there are lots of idiots out there preparing to do
exactly this.
My logics have failed me due to the above text: which of the following
you mean.
1) Any one who is preparing to do above will belong to a set called
"Idiots",
2) Only people who already belong to a set called "Idiots" are
preparing to do it.
Hey - don't take it seriously it is friday.
On a change note, what about the use of secure tunnels using IPSEC?
Won't that solve problem. Perhaps not in all cases.
I think you need - security, performance guarantee, network path
reliability and ability to control restoration paths. Security is only
one dimension to the issue of who controls the end to end delivery
system in critical applications. It is hard to be sure of an event
outcome if you are not in control of all variables that can affect the
system. Basic control theory. Do you think people who design these
systems flunked their control theory course (may be they concentrated
too much on computer science :-))?
