I'd love to get there, but I think building that consensus today would be a non-starter. Let me suggest starting with a lesser goal. Try to build a consensus that unless there is a good reason to do otherwise, it needs to be possible to write an open-source implementation of a standard and that the absence of such an implementation should be considered a red flag when advancing beyond proposed. Basically I'd like to start by getting to a point where we assume that open-source implementations are a goal and that we explicitly decide that they are not a requirement in contexts where that makes sense. I suspect we would run into resistance building that consensus but it might be worth trying. --Sam _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
