How would this even be enforced?
Simple. Use the DRM already built into Microsoft and Apple products, and you have control over 98% of the desktop / laptop market.
I smell a new flavor of Linux: Bitux
As soon as someone works the Kernel, I'm going to get to work on the dual boot install script for Windows users.
One has to be careful here since there are ex2/ex3/ex4 drivers for Windows so it is possible for the Windows system to wipe out files in the GNU/Linux dual boot. A similar thing can also occur with network shares on a GNU/Linux machine that can be written to from Windows. Before one starts to think of paranoia here there are a few things to keep in mind. Microsoft has provided the FSB (The successor the the KGB) with access to the Windows source code. There is also the section in the Windows EULA on malicious software. One must keep in mind that if the Russian Government deems crypto-currency illegal then Microsoft would be within their rights to remove any crypto-currency software,
including such files as wallet.dat, from computers running Windows in Russia. Then there has already been a precedent of Apple using the DRM in IOS to suppresses the teachings of the Dalai Lama at the request of the Chinese Government.
