Only if they can stop the whole world from designing hardware and
writing software. And that's too high a price for the world to pay.

Seems to me that if they want to transmit classified information
through uncontrolled routes, and make certain that only authorized people
can read it, DRM isn't going to do the job. Too easy for hostile foreign
powers to bypass it. What they need is cryptology adequate to withstand the
opposition's maximum resources, and an adequately secure method of key
distribution. The standard solution is a warrant officer with a locked
briefcase chained to his wrist, traveling by military aircraft with two
bodyguards.
For OGP, I think we have more than enough on our plate right now,
without worrying about digital restrictions management. If it ever got into
the TRV10 hardware logic, I'd think twice about buying it.
