The MOS evaluation is subjective, not objective and actually involves
getting (many) real people to listen to the audio, not just buying a
product. Of course, there's tools like PESQ that attempt to guess MOS
scores, but it's really just a guess. You can find these kinds of
results for Speex on the comparison page: http://www.speex.org/comparison/

My guess is that sending confidential information to a publicly archived
mailing list isn't exactly the best way to keep that information
confidential. Then again, it's just my opinion :-)
