You were lucky that Sprint would cooperate to this degree. Many ISPs
either won't make customer-specific changes to the service provider
routers unless it is a very large account, or add expensive charges
to do so.
If I understand you topology, it's a little different economically
from the one cited earlier. In that case, SBC was being asked to do
something that potentially could reduce their chances of selling more
bandwidth to the customer. In your case, it appears that you were
asking the dominant provider to do something that benefitted them as
well.
