Yes, and that's the reason why the 95% Windows-only share of the market is
enough. Change the numbers to 70/30 and the situation is very different.

No, it's a technological path. They're trying to restrict the ability to
make perfect digital copies of media. The next step is watermarking and
such, to close the analog hole.

Vista claims to provide secure media services of some kind, including
encryption of video on the PCI Express bus on its way to the video card.

My quick Google search hasn't turned up anything further, but I've read in
the past about standards that include encryption of the signal on the video
cable between the video card and the monitor.

Except when the closed source operating system vendor makes it not
possible.

This I agree with - DRM is fatally flawed for a few different reasons.

I was not clear enough in my statement.

The GPL is all about putting control of software in the hands of the
users, not the vendors.

Linux is released under the GPL, and as such it puts control in the hands
of the users, not the vendors.

The GPL does not make a secure multimedia path impossible. Open source
operating systems such as Linux make it impossible.

It would be impossible to ship effective DRM software with source code,
I think. And certainly pointless, since the software is no use without
the keys.

If this is true it would not surprise me at all. In fact, I'd be surprised
if the law *were* aligned with morals on this point.
