Well, not yet maybe. But it would be very impractical to have to 
convert to Ogg when the USA pressures the EU into accepting 
software patents.

Okay, now you have me confused (and curious). You can't use 
libvorbis for a project, but you can use any of the mp3 libraries 
out there. This can't be a license problem, since libvorbis is 
under the BSD license which is about as liberal as it gets. So it 
must be something technical. With Tremor now available under the 
BSD license as well you can do integer decoding too...about the 
only thing I can think of is that libvorbis would take up too much 
RAM at runtime? Why can't you use libvorbis?
