No subject

is somewhat split by this general issue of content protection through
cryptography.  On the one hand I went to a conference at the end of last
year where about half of the papers being presented were on various
schemes for content protection.  These were well-respected,
international researchers trying to accomplish something that seems
either pointless or just plain impossible.  At the same time, there are
other researchers who think, much as I do, that it's all a bit of a waste
of time.  When you give someone content for their usage/viewing on a
general purpose device (like today's computers), there is very little
you can do to maintain control over that content.  The only real
solution is to make the device itself less general purpose (i.e., more
restricted) which appears to be basically what Microsoft is planning on
doing with Windows XP.  Doesn't really bother me though -- I can't see
Linus accepting a kernel patch to only allow certain digitally signed
MP3's being played...

Regards,

Christian.
