RE: [TERNLI] Notes from tonight's ad hoc

I'm not sure how clear-cut it is.  E.g..  a path change might imply a
likelihood of a significant capacity and latency change.  A capacity change
due only to modulation change would likely affect the latency less
drammatically, I would think.  On the "other other" hand, the system could
generate two indicators on a path change :P.
