A spectrometer can easily measure the temperature of an object. the laws governing black body radiation (http://en.wikipedia.org/wiki/Black_body_radiation) are dependent only on temperature. If you can sort out the radiation peaks you see representing quantum energy level transitions, which is easy, since they look like peaks and black body is a curve, you can find the temperature of a radiating body.
I'm gonna put my email down here...

and find out how quickly spammers harvest it. I just hope it doesn't get modded down as offtopic so they never see this.
anyway...
The people who are buying aren't the people getting the spam. It's the people who keep hiring these goons to send it. The more people they have on their e-mailing lists, the better their marketing pitch: "we have 100 million live, tested emails, etc. etc." With this, they convince people to pay them to mail us. Everyone's getting scammed.
In this case, although anyone can argue that Linux can't die, as it is free, and has no single source to kill (for example, if red hat were to go out of business, linux would not die), linux could still be renedered inoperable on modern systems. Look at the recent furor over Palladium. This, and other proprietary systems that could be created in the future could either make linux unusable on a desktop, or make it practically useless for other purposes. Suppose Microsoft, or whoever, brokered a deal with ISPs to only accept packets coming from their proprietary, digitally signed, and hardware backed system that would not run Linux. Things are unlikely to ever be that extreme, but you have to understand that Linux can actually die...
Most spam coming in from Yahoo isn't from yahoo. Look at the headers. The "From" field is often _@yahoo.com, but look at the IP address it came from and the routing information. It's usually from some realy in a foreign nation who hasn't configured thier mail server properly.
Mostly, people aren't setting up 802.11 networks to provide 24/7 access to any particular person in their area. This collective wireless thing was more of a sharing the wealth, like, when I'm near your house, driving by or at a cafe or something, I can go through your DSL, and when you're near my house, you can use mine. The idea wasn't to give your bandwidth away to other people as a permanent connection... Oh well.
I can see how people would find this as perfect encryption between any two lin-of-sight points, but there are problems. Most signals that need to be encrypted aren't within LOS (which you need to send photons). So most signals will be traveling most of the way with perfect encryption (say, to the satelite, and then back to a receiver near the recipient) but anywhere else, the message must either be plaintext or use a different encryption. Also, all bounce points (sattelites, tall hills, whatever) need a system to set themselves apart from a phony, just like before.
