I didn't realize that, if I buy a Blu-Ray player (for entertainment, but more likely for PC)

- I'm giving content providers (and unspecified others) the right to continuously monitor what I'm doing with it

- I'm giving them the right to disable my player (immediately and remotely) without notice if they don't like the way I'm using it.

It looks like HD-DVD is leaning this way as well.

Combine this with the insidious effects of Vista DRM and we're all heading into a real mess.
