Etienne was asking for more channels in the
FLAC stream, so I was trying to put some meat
on Josh's bare bones statement that it "would
actually be a lot of work and require extensions
to the flac format".
Having multiple FLAC streams in an Ogg
container would, indeed, provide a second
level of grouping -- actually grouping in
chunks of eight, but that works. The problem
then becomes where to put the metadata.
The metadata could still go in the (multiple)
FLAC streams, as you suggested, but should
more logically be up in the Ogg container.
Currently, the only place available in Ogg is as
name-value pairs in an OggSkeleton stream.
After OggSkeleton has become well supported
then metadata can go into its own stream, but
we are not there yet. There does not seem to
be a neat solution.
