Default-free means quite simply, you don't have a default route, aka you 
carry a complete view of the global Internet routing table to make your 
routing decisions. Really it has nothing to do with being transit-free, 
nor does being transit-free have anything to do with whether a route is 
announced in the global table. At any rate, FYI in the previous list 
Teleglobe is not transit-free (which, btw is not the same thing as 
SETTLEMENT free :P), they receive a full transit feed from 1239 as 
verifiable through their looking glass. If you really care, you can start 
by looking at the Wikipedia article on "Tier 1 network" (which *gasp* is 
actually correct at the moment :P) for a verified list of settlement and 
transit free networks (aka Tier 1's :P), but again, this has nothing to do 
with anything.

Personally I think if you can't just say "Global Internet Routing Table" 
and have a complete and air-tight understanding of what is being 
referenced, we've got bigger problems. :)
