Unfortunately, some content distributors seem to be labouring under the
delusion that DRM = "we can invent arbitrary prising structures and
people will actually pay what we demand". Hopefully that will wear off soon.

I love the way that Steam won't let you log in twice, so you can install
the same game on two PCs, but you can only play it on one at once...
...unless you put Steam into offline mode. *facepalm*
Still, I guess it means you can't play *multiplayer* games from two PCs
at once...

Given that copying becoming easy is the problem... what's your point here?

Oh, that.

Yeah, pretty much. I gather zero-day cracks are a relished challenge for
some people. (Then again, most of the DRM I've seen surely can't be
*that* hard to crack in the first place...)

I don't think that's how it works. I thought the idea is that the
encrypted content is decrypted inside your graphics card, processed as
necessary (e.g., colour balance, or compositing it with the rest of your
Windows display), and re-encrypted before leaving the pins of the chip
in the circuit board. So the encrypted link from the graphics card to
the monitor is a completely seperate cryptosystem from the encryption on
the disk (or whatever).
Ultimately, what it all boils down to is that the piece of electronics
in front of you knows how to decrypt the video data. Which means that,
in theory, you can do this too. The keys must be stored somewhere. It's
merely a question of how awkward it is to do, as a practical matter. As
you say, you've only got to pull it off once.

That's basically what it comes down to, yeah. Software running on a
general computer system that you have full control over? It's toast.
People paying money for computer systems that purposely prevent them
doing stuff? Not gonna be popular. :-P
