Thanks for the feedback

I was just thinking about what I can gleen from the messages so far and 
thought of the old saying: why invent something new when something old 
would suffice.

I don't know if COPS will address your requirements, but was initially 
curious if it had been looked at, even if it needed some extensions to 
solve what you were looking for in the control plane.

The next thing I was thinking is that if COPS had been ruled out, why was 
it ruled out.

There likely are some perfectly valid reasons to rule COPS out, I was just 
wondering if the list was going to see that reasoning - and it sounds like 
we will.

I look forward to reading the ID(s).
