I guess what route views sees only minor bearing on what's out 
there.

There are at least half a dozen or so publicly advertised relays that 
just for some reason don't show on route-views.  And if you look at 
Abilene, you see at least four as well.

For example, if you look at http://stats.geant.net/lg/lgform.cgi, you 
can see 4 relays, and that's even not the full list of them (at least 
ours, from AS1741 through AS2603 [NORDUnet] doesn't show up there, 
maybe GEANT doesn't allow it anymore for some reason).
