we have at the moment only the situation in which non-fault-tolerant
systems address our fault-tolerant system. Our emphasis is currently
only to detect a fault, switch MAC and IP address, report the fault and
let the outside world believe all is fine. We have then 1 to 4 days
time to fix the faulty system. Yes, I know, this is not a very common
situation. We use this only as users of the system have to have no IT
skills. They even wonder that there is some IT used in our system.

I can imagine where you come from. Your system is very, very different
from our system. Just have a look at our website. The words IT,
computer, fault-tolerant etc are not even used a single time.
