Adrian,

One of the neat things about this running code thing is that what ends
up really counting is who wrote some running code or worked to deploy
that code in a network particularly when the majority of vendors have
done the same thing and they all interoperate.  That's the case here.

I agree with you that we should clarify RFC3209 and preferably put the
clarification in a future iteration.  Perhaps it would be easier if
you suggested wording for the next iteration of RFC3209 and if the
authors agree to it, we won't need a separate document.  But if you
feel that's not the way to go or insufficient, go ahead and write an
informational draft with the clarification and a crystal clear
definition of hard preemption and soft preemption.

Thanks,

Curtis
