You will not learn hatred until that MMO you host implements a 'Report 
network problem' button that does a traceroute, and automatically emails 
it and a canned message to your NOC mailbox. Ultima Online did this, back 
in my nocling days. Like monkeys expecting a reward, those little bastards 
pounded on that button until the lag stopped.

It gave the west coast sucking sound that was Mae-West an entirely 
different flavor. We could monitoring peering conditions based solely on 
mailbox volume.
