1. Deaggregation to help spread out traffic flow. As someone who used

   even MEDs that make sense, can help with decisions regarding which
   part of a /9 can be reached best via which peering point. (And
   that's peering as in BGP, not peering as in settlements.)

Legend speaks of a well known BGP community referred to as 'no export',
which causes people with no direct connections to $carrier to not
have to listen to all that extra junk while still engineering inbound
traffic w/ more specifics for people who peer directly in diverse
locations.   Amazing!


2. Cut-outs for those pesky dot-coms; you know, the ones with the most
   compelling content on the Internet jumping up and down in your face
   with a need to multi-home their /24 to satisfy the crushing global
   demand for such essentials as "the hamster dance."

Ignoring inconsistent-as for a moment, the hamster dance multihoming
doesn't make the parent upstream need to _originate_ anything of the sort.
