It's not so much the advertising I object to, but all the "conversation" that gets repeated each time the issue comes up. Give it a rest. Stay on the topic. Keep your laser handy. Anyone get very far with the CELP stuff yet? I forget: is it or isn't it "acceptable use" to implement Diffie-Helman in code you don't sell? What if you sell it later? At what point do you need to license it? /jordan
