I'm sure Bradley, Crow, Hugo (and more?) have a much better understanding of 
frequency shifters than I do. I think your general concept is good, but I 
think you will lose the pitch relationships by this method -- you know, the 
sum and difference thing as opposed to the doubling relationship of octaves. 
Does this make sense?
