Russ,

As unlikely as such a failure is, I was thinking more along the lines of a
huge disaster occurring for a major medical facility. Lets say its the core
of a hospital system, or something of the sort. As it is today, its likely
that the second to second life and death decisions made in hospitals is not
entirely regulated by machines. . . not yet that is, and the human element
would prevail.

We can all think of worst case failure scenarios and terrorist attacks,
however, those are not the ones that keep me up at night. My fears are for
the little details, the gremlins that love to hide between the lines, in the
tiny little spaces and then boom, something major happens.

I guess in balacing it out, its always about cost. However, if you were to
tell me that money was not an object and that this thing needed to be totally
redundant, accross two or three sites, in different parts of the
country/world/regional solar system, then I would have to go with prudence
and opt for some solution that would allow one site to be totally obliterated
and have the others pick up without a hitch.

Then again, the moon is made of cheese!
