Minor correction there. If you are talking about our IX collectors (LINX, PAIX, EQIX Ashburn, SYDNEY, etc.) those are at exchanges and peering directly. The collectors at Univ of Oregon (rv,rv2,rv3,rv4, rv6), yeah, those are multi-hop. Doesn't detract from your point, but I think it helps if people are aware of whether they are on the exchange or on a multihop when using routeviews collectors.
We talk about routeservers, not collectors. Argus doesn't use routeservers in RouteViews to identify hijacking.
Only other thing to add, I don't think anyone mentioned Cyclops in this thread. Just as another data point, see also: http://cyclops.6watch.net or http://cyclops.cs.ucla.edu
