would say your suggestion could leave out virus infection....that being on life support that depended on Windows would be scary enough.
My employer's network recently suffered a major viral attack. I don't remember the name of the virus, but I think it was the same one that attacked CNN recently.
It looks like most of the damage has been repaired now, but some glitches still show up from time to time. Some of the servers apparently had to be replaced and several major pieces of network-wide software (like Citrix) had to be re-installed.
I don't know what the virus did, but it was apparently pretty vicious.
It has taken IT over a week to get most of the systems up and running.
Somehow this does not inspire a lot of confidence in the reliability of medical record systems when they become a reality.
Maybe hackers should be punished by placing them in self contained modules with life support controlled by virus-infected Windows systems?
