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?

This letter is not intended to start a flame war about patent rights, licensing, or anything similar. Reply directly to me. I've spoken with Jim Bidzos, president of RSADSI, about this very issue recently. They have a very easy to understand principle that governs the use of their patents. I am rephrasing it; at no time was this actually spoken. It's very simple: "If you make money with it, so do we." Their licenses are not out of line with patent licenses generally (and not just computer-related ones). If you make public domain software and use it for personal use, RSADSI will not come after you. If you make commercial software and sell it without obtaining a license, they will after you. If you use the software as a "mission-critical" part of your business and do not obtain a license, they will come after you. There are grey areas between these two poles. I do not address them. Eric
