Yes, I saw that. Having read the patents, they seem to be extremely  
inclusive - I can't think how one would develop any rateless code  
that isn't covered by them.

The only reason I haven't contacted him, however, is because I  
assumed he had some reason for not publishing his patent-free code,  
and wasn't just going to hand it out to whoever asks. :/
