If you have pathalias, do some runs with different costs for uunet in your
site's map entry.  We found that if we set the cost to EVENING, pathalias
would generate a route through four machines to get to uunet, instead of
going direct, because it could find a route to a site listed with uunet as
DEMAND and it was cheaper by pathalias' criteria.  This largely defeats the 
purpose and I don't think imsl wants to pay for our uunet traffic.  Thus,
if everyone lists the costs the same for uunet, the "closest" machine to
you should be the one that calls uunet, and any site that has a uunet connection
will get their stuff routed through it.
