Source code availability is not the issue; the reference source code is 
easily obtained from the ITU-T. Many of the G.729 patent holders are 
companies based in Europe, so I suspect they would have a different 
opinion than you do about the legitimacy of their patent claims on G.729 :-)

In any case (and of course IANAL), it is my understanding that the 
patents that cover the base G.729 recommendation, along with Appendices 
A and B, will all expire in the next year or so. We'll have to see what 
that means for the market, especially with new, more freely licensed, 
codecs coming out that provide substantially better performance.
