You are right. I think everything should be using fixed point, because only 
lamers use floating point, it's a horrible idea.
Regarding the vorbis benchmark, it sounds interesting (I would be even more 
interested in how ffmpeg would have compared). It is mostly the same code 
(tremor and libvorbis), so I am somewhat puzzled at the result you are
