FWIW, here's my response to an earlier private enquiry from John on the 
topic:

  I'd prefer discussion to be public, so I don't mind leaving more 
  detailed discussion to that.

  There has been considerable discussion on the issue, following Linus' 
  statement (which I'm sure you're aware of):

  http://marc.info/?l=linux-kernel&m=105115686114064&w=2

  My position is similar -- people can decide for themselves whether they 
  want to use DRM technology.  I'm also confident that technical measures 
  taken to prevent real freedom will always be broken (when have they ever 
  not been?)

  I also feel there may be genuinely useful applications of some of the 
  technology (e.g. sealing disk encryption keys in the TPM a la 
  BitLocker).

I'm fairly neutral on the technology itself and feel that "market 
pressure" from users as well as local regulatory policy (e.g. anti-trust 
laws) should determine how the technology is used, rather than the views 
of a few kernel hackers.
