Couple of random thoughts on the subject:
This is the only car I have ever owned that has no coolant temperature gauge.
So I use torque pro to monitor water temp and air intake temp... this helps to learn typical patterns in which the system behaves depending on different conditions and any unusual fluctuations may indicate a potential problem before it happens, I hope.
Also I think it's worth mentioning that certain tunes (Dinan comes to mind) do raise water pump operating speed. And this has to have an effect on its longevity, I think.

And sort of off subject - I own a 25 years old italian-made espresso machine that I use everyday twice a day and I have replaced a few failed parts to keep it going, but the electric water pump is still original and still pressurizing the thing to 15bar like the day it was taken out of the box. Go figure...
