Its not my style to advertise our stuff on other MLs with 'similar' 
goals as matroska, but please note we have ON2 VP3 ( VfW ) working with 
several Vorbis audio streams in matroska since a couple of weeks now, 
including DirectShow parser filter to play it on Windows platforms.

Dont know where you get the impression we had to make a 
'proof-of-concept' first, the matroska file creation tools were tested 
since many weeks and released to the public on May 1st, and this 
includes a modified version of Virtualdub to create, preview and edit 
matroska files. For Linux Moritz 'mosu' Bunkus has done a wonderful job, 
his 'mkvmerger' tools are state-of-the-art, files created play fine on 
Windows also, and the mplayer playback patch has made its way into 
mplayer main CVS although libmatroska is C++ . All files were found to 
be spec compliant, and users actually start using it to archive their 
movies in matroska.

Of course, i know that Theora and ON2 VP3 are divergating and i seem to 
recall Theora will not have a VfW API anymore ( which makes sense IMHO, 
VfW suxx bad time for modern video codecs meanwhile ), but we will 
certainly not implement Theora support into our encoding tools before 
there is a new, opensource codec API to use and Theora supporting it. It 
makes no sense to hardcode every single codec based on its own API into 
a video encoding app if a plugin system can achieve almost the same 
performance, and in a much more flexible and user friendly way. Maybe 
the Theora codec API can become this long awaited open codec API 
standard, we will examine it closely once it is released ...

About the original idea, to use matroska for Theora, thats of course 
complete BS ( sorry ;) ). Ogg is a very good container for the codecs 
that Xiph are using. Its a matter of consistency to use Ogg for all 
upcoming Xiph codecs, and if only to be able to use the existing Ogg 
streaming server solutions like icecast and shoutcast.
