Hi Kevin,

Come on now. At least *try* to get your act together before replying.

Its copyright code. What you agree to is irrelevant. The copyright 
stands anyway. That is the law pertty much everywhere. No registration 
of copyright or agreement to copyright is necessary.

As far as I know there is *no* other implementation. The Intel code, 
VoiceAge, and everything else I have looked at can clearly be seen to be 
minor derivatives of the ITU reference code. Can you actually point to 
another implementation?

Try looking before shouting your mouth off. You have to build the code 
Intel supply from source. You don't get the source for the Intel 
performance primitives library itself. You get the ITU G.729 reference 
source code modified so it runs faster using their IPP library.

$200 lets you use the IPP library itself in commercial applications. The 
G.729 source code is supplied purely as an example of how IPP can be 
used to speed up the ITU reference code. Intel offer you no rights to 
that, because it's not their to begin with. They give you similarly 
modified source code for G.723.1 if I recall correctly.

Usual clueless drivel. Try looking at patent law a little before babbling.

On that much at least we agree.
