Actually, they ARE the correct costs.  Sdcsvax doesn't place
long-distance calls at all [for political reasons that are
(regrettably) inargueable and complicated - sigh].  We will hold mail
for hosts such as ihnp4 and the like, but ITS UP TO THEM TO POLL US We
have made our map entry (reproduced below) as reflective of our
real-world connectivity as is possible; for the hosts that we do call,
we clearly indicate that, and for those who call us, I have used the
3-month average of poll frequency as shown by our uucp records.  As a
reminder, DEDICATED means highspeed direct connection, DIRECT means a
local call placed on demand, DEMAND is a long-distance call placed on
demand (we use it for internet and X.25 connections), EVENING is a time
restricted call (in this case, the only toll call that sdcsvax does
make - to ncr-sd, the people who were complaining above), and all the
rest we show are incoming-poll-only connections - they call us, we
don't call them.  In many cases, this takes advantage of these hosts'
WATS or extended-area dialing coverage that we simply don't have.

This, to my mind, is a whole lot closer to reality than most of the
hosts out there that claim free connections to the entire net.
