I understand this argument, and it is much more general than security. However it is not how the IETF works. The goal of an IETF spec is that you can take any two implementations and use them together. They may not support all features but they will work together. Security is not a feature, it is a requirement. --Sam _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
