Of course, he has to discover my laptop's MAC (which he can probably
do with an ARP flood), spoof it (easy on Linux, dunno on Windows), and
DOS my 'top (probably hard, unless he has a botnet).

So yes, my network is insecure. But then again, so is any network
connected to the outside world. :)

But I think my layer of making shite difficult for the bad guys is
enough to ensure that the wardriver chooses one of these nice networks
instead:
