[CCing Trond and Bruce]

Dan: To answer your question we have everything that you want already in the prototype. In terms of getting it upstreamed Trond and Bruce want to see some consensus from the standards body before they consider upstreaming the code.

Trond & Bruce: I am going to be at IETF 73 in a couple of weeks are either of you going to be there? I'd like to have a meeting with you about what it is that you want to see happen before mainlining. This way we can come up with the criteria we need to meet before we can mainline the code. If neither of you are going to be at that meeting can we organize some sort of telecon to discuss this?
