Mmmm... Could be a very improvement for the sound streching. I've some 
problem with SoundTouch (compiling and latency issues)... So I'm 
interested... but from what I can see from the project page, there is a 
"donate" form but no CVS or code package!!!!! This is quite strange IMHO... 
I hope in the future.
