Though much of that has been bad PR handling, I think. It's not as if
Intel invented that feature - for example, every s390 system has one (and
so did the whole family at least since the /370, used for licenses, for
example), and everything living on ethernet is supposed to have a unique
MAC address. (Which *has* already been used in tracing authors of
malicious Windows software, I believe.)

OTOH, ISTR that under VM, it's possible to simulate the /370 etc. cpuid of
someone else. Which I know has been used to circumvent license
restrictions.

Then again, the US custom of using the SSN as a generic index would be
rather illegal over here, so that might change peoples attitudes to the
mere existance of those numbers - it does make a difference how big a
stick you can wield.

Not that any of this is important to Linux ...
