i think both are capable of tagging their customer routes, then you can
apply policy based on those communities to balance the load a bit

you can also pref based on asn and/or prefix...kind of ugly, but it is
essentially all the magic routing boxen do, to distribute the load.  pref
short as path, pref 0/8 through 64/8 to one, 65/8 through 128/8 to the
other, etc etc

bgp picks the oldest path, all other things being equal, because that
implies a more stable path.  unless bgp is picking the very wrong path, i
personally don't like to muck with things like this
