And your review on this is...?

wow,  technology  is  awesome ,  been  awhile  := )

I read about this once. I think it was on Cnet. The article said that other scientist weren't impressed. They said that this technology has been around for awhile and it simply never went mainstream.

It was on the yahoo homepage maybe a year ago. I wouldn't use it because I like my range and I've never had a problem with hackers.

The article says this blocks cellphones so that's another reason for me not to do it.

Really? I didnt see that it blocked cell phones. Hmm that sounds like some very crucial information to leave out.

The paint isn't just of interest to those concerned about wireless leaking out of the building. Movie theaters have long been interested in finding a legal way to keep cell phones silent during screenings. Electronic jammers that actively block wireless signals are illegal, but passive materials that prevent wireless signals from getting through are not. Since the wireless-blocking paint can also block the lower-frequency signals that cell phones use, addled mobile junkies would have no outlet for reaching the outside world.

Uau how is it possible that Paint can be used has a " Fire Protection" , who would think on Something like That.
I would Not for sure.
On my Knowledge i knew that  , walls , microwaves , Iron Towers , refrigerator's could interfere with Wireless Signal but Paint...
Where are we gonna Stop?

If the paint doesn't burn, then it will help prevent fires from spreading much.

The technology to block RF signals has been around for years, probably going back to the forties or fifties.  Many things have been used from lead lined rooms, to fine copper mesh, to the metal impregnated foam used on stealth planes.

It would have been nice if the article gave specs on how much RF blocking the paint could do.

Also, what about the floors or the ceiling?

And ...

Trap doors.
Electrical outlets, light fixtures, wallplates for Ehternet.
(The opening is larger enough to pass microwaves.)

But there is another technology. You just run a wire from each computer in the same room. Just a single wire. No hub, no Ethernet. It is wired microwave. Not new. Just nobody likes it.

An yet another technology is advanced infra red.

Yes, old story. But so is the technology in the topic.

Seems like to much work just to block your WiFi. Rather encrypt it with a password or something.

How is WEP secure?

Seems like this could cause problems within your home. I wonder how much testing has been done on it.
