The original question I asked was simply if MPEG support had ever been added
to the <linux/soundcard.h>, as some of the declarations therein seemed to
suggest that such support would be added.  I didn't ask for a lecture on
whether or not it is appropriate to add such to the kernel

As it is, I concur with the posters who wrote that this is not appropriate
for the kernel.  The kernel is big enough as it is, but, more to the point,
this is just something that needs to be done in userland or, perhaps,
implemented as a loadable module if you the need for kernel access can be
demonstrated.  There appear to be several good libraries for achieving the
sort of speed necessary for decoding/encoding layer II/III files, so I don't
see the need for more bulk in the kernel.

My $US 1/50.  Thanks to those who replied.
