On a related note, I recently raised the issue of Ogg in relation to the 
W3C's XHTML 2.0 Working Drafts.  See XHTML 2.0 issue 7358 
<http://hades.mn.aptest.com/cgi-bin/xhtml2-issues/Object?user=guest;selectid=7358>.

Basically the draft uses GIFs and MP3s in a lot of examples; I suggested 
that PNG, Ogg Vorbis and Ogg Theora might be better formats to use, as 
they are more in line with the W3C's patent policy.  The present comment 
from the HTML Working Group is "I changed a few of the comments/examples 
but I did not change the mp3 references -- at least mp3 is a well known 
format."  :o(

(If anyone wants to raise this with the W3C, details of the two HTML 
mailing lists can be found here: <http://www.w3.org/MarkUp/#forums>)

Cheers
