A Reg piece on the Microsoft/Intel/AMD "Palladium" DRM/security system in
development, and how it could
kill the GPL. Basically, to work with DRM content and the "trusted" hardware, binaries and kernels will need to be certified, which makes the whole idea of open source useless. (You can compile your own, but it won't work, as it won't be certified.)
By the way, note that with the announced fall of KPNQwest, DRM will soon be useless in Europe since there soon won't be enough network resources for anything else than ASCII for monthes.
