[speex-dev] fixed point conversion volunteer (OMG what am I doing?)

I'm willing to contribute some time to converting speex to fixed point.
I'm not doing this for a particular product and I will receive nothing but
some warm fuzzy feelings for "giving back to the community".
Consequently, I don't want to do it all myself.
So ... is anyone else currently working on this?
Splitting the work into chunks should allow more people to write code when
I haven't known about speex for very long (very cool project -- much
needed), so I'm not very familiar with the code yet. I did code fixed
point replacements for a couple of the functions in filters.c, but I
haven't put much thought into how to organize these into the mainstream.
Has anyone already done any analysis on the dynamic range at various
points of the processing? Stability of the IIR filters?
<p>Also, if anyone has a preference for common code or fork. Which and why?
<p>PS. I have 8 years experience optimizing C (as well as C++ & other) code.
Some of that experience is on fixed point DSP processors.
