putko asks: "Intel has a new line of chips with DRM built in. This
appears to be the very first DRM-enabled chip to hit the streets.
This microprocessor is unlike others available, because the user
doesn't have complete control over the thing, and your computer can
(theoretically) betray you. For a while now, there have been computers
(IBM ThinkPad) that won't boot unless you give the password, but you
could always rip out the hard drive and read it, right? With this
chip, the keys and RAM are on the chip, and the flash is encrypted, so
this really looks locked up tight. Has anyone worked with this chip,
and is possible to build your own device that uses the Intel Trusted
Wireless Platform to protect your secrets (like your software,
"I'm reminded of this due to Slashdot's recent story on the iPAQ,
which uses the chip (and has some neat security features too).
Somewhat surprisingly, nobody brought up the Doomsday scenarios,
there. It should also be mentioned that there are companies selling
incredibly tiny boards for it. Maybe you can run Linux on them?
Wouldn't it suck if the chip had the capabilities and you couldn't use
them in your own projects -- e.g. if that was just reserved to big
companies like Microsoft? On the other hand, if you can use the
features, you might see some neat applications. Assuming you can
program the DRM stuff, how do you avoid locking yourself out of the
chip while developing? What extra pitfalls may developers run into
