You need to update this part: "Anecdotal evidence indicates that most 
Windows users play audio using Windows Media Player, which doesn't 
support Ogg Vorbis files by default (though I'm told it's possible to 
get support working, at least with older versions of WMP)."

It is very easy to get vorbis working with Windows Media Player 
(although I don't do it that way, Winamp 2.8+ is better).  It actually 
works the best with WMP 9 in my opinion.  In previous versions you could 
play but not do a playlist.  All that is required is that you download 
and install the DirectShow Filters available at tobias.everwicked.com.  
It is a very painless install.  It actually makes it so almost any media 
player in Windows that uses the built in codecs (ie ZoomPlayer Media 
Player Classic, etc) will play Vorbis.
