Yes and no.

I tried it but not seriously. I only went as far as floating point
emulation, not trying to understand the algorithms and turn them to
fixed-point/integer. I have been watching the ogg-vorbis lists though, and
it would seem to be only one part of it that remains to be properly
integerized. Unfortunately from the sounds of things it would take someone
who really knew what they were doing to transform that last bit. I don't
remember what it was, just that when I Googled for the definition what I
found made very little sense to me.

The emulation proved insufficient as the quality was way, way, way down. And
the normal floating point emulation (e.g. the automatic stuff) wasn't fast
enough.
