as in the room, I'd hope to focus on-list on:
   "What is a route-leak?"

I thought that a taxonomy:
   "a scheme of classification."

of what route-leaks/hijacks are would be helpful. It's possible that
we could call all 'hijacks', 'mis-originations', 'valley-free
violations'  the same thing: "Route Leaks"... but having a definition
and a method to view these from either a direct neighbor OR (ideally)
2 as-hops away would be much better.

Sriram/doug's document talks about 4 types of leak, of these 1, 2, 3
all basically look the same to me, the original set is:
   1 - prefix-hijack with path to legitimate origin
   2 - u-turn with more specific prefix
   3 - u-turn with full-prefix
   4 - internal-prefix-leak

To me this sounds like:
   1, 2, 3 are all saying the same thing: "Someone leaked all or part
of my prefix, but provided transit to me anyway"

and 4 is mostly lost to me... though I suppose it might mean: "my peer
leaked my prefix to his transits"

The goal for this work really ought to be:
  define route-leak

Then the next follow-on is:
    "Do operations folks view this thing as defined to be a problem?
should someone fix that problem?"
