House Paint Foils Wardrivers

Ant writes "Security-minded U.S. decorators' supply outfit, Force Field Wireless, claims to have developed a do-it-yourself solution to the international menace of marauding geek wardrivers: DefendAir paint 'laced with copper and aluminum fibers that form an electromagnetic shield, blocking most radio waves and protecting wireless networks.' According to the South Florida Sun-Sentinel's report, one coat of the water-based paint 'shields Wi-Fi, WiMax and Bluetooth networks operating at frequencies from 100 megahertz to 2.4 gigahertz", while two or three applications are 'good for networks operating at up to five gigahertz.' However, there are downsides to this." Since it's a water-based paint, exterior use is only recommended for people who want more copper and aluminum in the soil surrounding their house.

What about cell phones

Would you have to climb up the chimney to call your friends?

I object to the on-call people being in movie theatres. Go see the frickin' movie on the night when you're NOT on-call.

I like the way some people assume doctors are not allowed to have a life. It's ok to call the doctor whenever you like, day or night, but it's not ok for the doctor to go out and watch a movie? The doctors I know leave their phone on vibrate, sit at the back of the theatre, go out to answer a call (more often it's an SMS which they can answer sitting where they are). Exactly what's wrong with that?

Some doctors are pretty much on call 24/365. If you're the only [FOO]ologist practicing within 200 miles, you take calls whenever someone has a question. I'm not talking about small towns in the middle of nowhere either. There are lots of subspecialties that only have one practicing doctor serving a population base of millions.
Not that they're the problem. It's the teenagers who thing they're some kind of socialite and can't wait an hour to find out who dumped or hooked up with who. Or even worse, the idiots who think that having a cell phone makes them part of the elite, and they spend every waking moment showing it off.
Theaters who really care would post notice that they kick out people with ringing cell phones. No refund. Then follow through.

Some of use are on call 24-7. For example, I carry a Blackberry where I get messages related to things like dropped pings on a critical production server. The Blackberry is always on vibrate, and I doubt that the slight buzz would even be heard by anyone in the theater. At that point, I can decide whether or not I need to leave, or at least begin to plan what I will do when the movie ends. If I do decide to leave, I am no more of a bother than the tons of people getting up to piss every 15 minutes.
I would purposely avoid movie theaters that blocked my signal.

How useful!

This is great, unless you YOURSELF want to connect from the outside, like from your backyard.

What about windows, ducts, etc.?

[Krankheit]

How will you cover areas such as windows? If this doesn't cover the windows, war drivers are not foiled.
