"Secure Blue" from IBM

A few days old but still interesting.

  IBM plans to announce availability of the new technology,
dubbed
  Secure Blue, on Monday. The Armonk, N.Y.-based company
envisions its
  idea and technology will be used in digital media players,
electronic
  organizers, cell phones, computers and devices used by the
government
  and the medical and financial industries.

  With Secure Blue, data is encrypted and decrypted as it
runs through a
  processor, according to IBM. It is maintained encrypted in
the device
  memory, or RAM. One of the few times data would not be
scrambled is
  when it is actually displayed.

"Easy enough" for ephemeral data (RAM, network,
...), but what do they
propose for stored data? Is this an architecture for
general-purpose
computers, or for special-purpose media devices? Is more
detail available?

As soon as data is stored, new key management issues come to
the surface.
I for one would not want to lose my hard-drive if the CPU is
fried...
