This sort of thing has been used for years. For example, it was in the
DOS version of Attache accounting software. You hash some values
that can be read from the machine such as RAM size, hard disk size,
CD-ROM make and model, hard disk model, serial numbers of devices,
etc and get a magic number that is unlikely to be the same if you do
the same calculation on another machine. There is no way to go back
from the key to the values used to create it (I have the number
9456345789 in front of me - please tell me what numbers were summed
to get this value).
You can reinstall on the same machine without any problems, but you
have to register again if you change major components on the machine.
People worried about privacy invasion might like to consider what
registration is for (and you can always give a false name and address).
I am a bit surprised to see that the experts and conspiracists have only
just discovered this, since it has been in Office 2000 for the last six
