You have to be/have been a pilot or navigator to captain an aircraft carrier. (I wrote a paper about this in the 90s...) and the US hard-on for aircraft carriers ain't going away anytime soon.

Good point, I'll have to read the article.

Ya :( This was better http://hackaday.com/2012/12/18/build-a-360-synthetic-aperture-radar-with-mits-opencourseware/

It was done with USRPs (http://www.ettus.com/ which are awesome) and one of the WiFi encoding schemes, not with standard WiFi hardware :(

The paper http://people.csail.mit.edu/fadel/papers/wivi-paper.pdf

Gimme! Please :)

Building Skynet is also a priority.

We would do both...

At some point stupid people won't be able to unlock the gun in the first place :)

I AM NOT ADVOCATING THIS. You just asked what problems it solves and someone asked how will they force people to get new guns.

Those are the problems I see as preventable by the ALLEGED features of this technology. (I am pro RKBA). They happen, I am not sure how many per year. (Honestly I don't care, because my guns are secured)
It is not going to stop most mass shootings, murders, negligent discharges, ...

That is why they want to have a law to make everyone buy one. It will take a while to get the old ones out of circulation...

It solves (probably poorly) the problem of police officers being shot with their own guns and kids getting shot by guns their stupid parents left accessible.

They just need data, yahoo can then process it and build up an accurate model of you. People are more honest on tumblr...
