	Can't anyone who takes full routes from any tier 1 provider 
operate without a default route? And isn't it a reasonable assumption 
that if you don't have a route somewhere, odds are they don't have a 
route to you (assuming you do your own BGP routing) and so a default 
route is mostly pointless anyway?

	What am I missing?
