Richard,

A fair point. That said, I travel around Asia quite a lot and I find that
when I'm plugged into a hotel broadband network, in some countries, my
laptop is being thumped by port knocking and various attempts to get in. 

I was in a hotel in Korea about a month or so back and my machine was being
so badly hit that the CPU was running at around 40% even without me running
any other apps. 

F-Port helped to track down a Trojan that had been dropped in which wasn't
picked up by the virus scanner. 

Cheers,

Adam
