	Using the always-compare-med and deterministic-med
whould aide in the outbound balancing.  if you get a route update
which changes the metric to be a better path, you will switch
your path and advert this change to the rest of your bgp speaking
devices.

	You may also want to just do simple metric math
or stomp the metrics received by your upstreams
to let as-path be your only decision maker.
