	I always local-prefed paths to other upstreams down via a
specific upstream in my 2x removed previous life.

	made traffic flow the "best" path and was useful when you had
a connection (but not directly to ANS, one of their "sub AsES") w/ ANS
and wanted to insure that traffic to ANS went over your ANS link instead
of via 1239, 701, or 3561 because of as-path win/tiebreak.
