#2So this was basically an S-band radar with a home wifi router? Can we make a mosquito zapper lazer with it?

You could probably, it wouldn't work very well. Either way, Nathan Myhrvold, evildoer and all-around asshole, would sue you for patent infringement. I recommend making a Myhrvold zapper laser first.

#4>A standard Wi-Fi router could be adapted to function as a receiver.
The article and the embedded video do not make it entirely clear but if this technology could be deployed in existing Wi-Fi routers with relative ease [1] then it could have far-going implications for both privacy and the physical security of anywhere where there's Wi-Fi. Once it's easy enough to deploy on a hacked device that a hired script kiddie can do it even simple burglars could take an interest in residential routers to know when nobody's home.
I wonder if this will affect the market for embedded Linux security consulting in a major way.
[1] I.e., without modifying the hardware and with no need for manual calibration.

#6Oh the possibilities of this - may be with enough data
- you can just wander around a suburb and figure out which houses are currently occupied and which ones are not.
- improve aged care by monitoring walking patterns
- combine it with some more ingenious technology for localised sound -- you can beam music as I walk around the house (or block out sounds)?
- a bit more sensitivity and we can even probably pick up a person while they are having or just about to have a heart attack?
I am sure the privacy folk out there are having multiple heart palpitations.
All I want to say is "bring it on"

#7If used right, this would disrupt home security industry so hard. It would be possible to get rid of any motion detectors, if I am not mistaken.

#8This may not be something we want.

We already did that in 2007 :) https://www.youtube.com/watch?v=wSIWpFPkYrk

If I understand this correctly, you would really be replacing one sort of motion detector with another.
The article is talking about phased array stuff, stuff you can't do with stock wifi equipment. All the regular wifi equipment is just providing the "light" the special receiver needs to see.
