I'm not sure the WEP thing is that big a deal unless you're in a tower block peopled with hackers.
I don't see many suspicious vehicles sitting round here with shady characters and laptops (apart from my daughter, occasionally).
I use WEP, with fixed DHCP for my own machines, and a list of MAC addresses allowed to access it (so the family can use it when visiting). It's simple, and I don't have to mess with it from one month to the next.
A determined hacker could listen long enough and find a MAC address that's allowed in, and spoof that. But then, he could bash the door down and help himself to the computers, too.
Up in Norfolk, I can see four : one WEP, two WPA, and one "open". The chap with the "open" one says "yes, it's for my neighbours each side."
