(from, er, probably libFLAC)) and oggz (from liboggz) ought to be just
what you need. oggz tools will merge tracks togehter and allow changing
comments in them. However, FLAC have their own tagging system, but
I think it's Vorbis comments based too (don't quote me on that though).

Sure. We do lots of things that aren't supported by media players yet :)

I don't know enough about these programs to comment on anything but the
wording: technically, they (probably) support multiplexed audio, allowing
a stream to be selected. I'd say something like "they don't support dynamically
mixing several logical tracks from the input stream" to make it clear what you
are after.
