You're a good devil! ;)

I still have to wonder if g.729 is measurably "better" than Speex or
any other 8kHz CELP-based codec. What is that measurement? That's how
you can tell if it's "worth it" or not. As for me, I'd rather not get
locked in. Patent encumbrances are nasty and I prefer to avoid them
where possible. I think bigger businesses are starting to wise up to
that fact as well. I think Polycom's model is going to catch on:
codecs are "basically free" but are not open source. Not my favorite
option but if I get a license to use the codec in perpetuity then I'm
feeling pretty good.
