How many is enough? As far as I can see, adding more servers just makes the
window smaller. You might have an interesting point, but you haven't
provided any numbers to show that it's practical to add enough servers to
make the window small enough.
Is monitoring really going to solve the problem? What are you going to do
when you notice something fishy going on?
These are my opinions. I hate spam.
