I think  Vijay's message reveals  a presupposition about the  business model
which  is worth  pointing out,  viz., that  Internet access  is  the primary
business and VPN service a side line.

All Internet routes  are brought to the edge because  "a couple of customers
insist on  having full routes".  And  one doesn't deploy  equipment "just to
aggregate VPN customers". 

If one's business were primarily VPN service, one would be a lot more likely
to say  "I'm not going  to bring full  routes to the  edge just for  the few
customers which  want them; those  customers are already running  EBGP, they
can just run it multi-hop". 

I'm sure someone will respond that there are no SPs who are primarily in the
VPN business and only secondarily in the Internet access business ;-)
