supported in matroska already, and in any combination and unlimited 
number of tracks.

I know this all, in theory, could have been done with MOV also, but i 
dont know of any existing software that actually does it ;) ?

About Arpi's rant( C++ ) : we have a nice working C lib now, made by 
Ronald 'BBB' Bultje, in L-GPL. Its the base for his matroska gstreamer 
plugin, and in gstreamer CVS.
