Point: there's a body of data that indicates "multihoming" is not the
culprit. There's a lot of needless de-aggregating that has little or
nothign to do with multihoming, and mostly to do with lack of clue.
Both WRT limiting the scope of provider-based so-called "traffic 
engineering" (CF ptomaine drafts) and that folks not using large tracts
of space can return blocks and get blocks that actually *fit* their
need.

Unfortunely there's a few companies/consultants  whose business plan 
requires them to graze on the commons and get all in a huff when any of 
us tell them they're filtered because they are causing incremental damage 
to our networks. Get over it kids; stable and deterministic behavior is
required for IP to work optimally. 

Stability uber alles,

Joe
