Since this could be dynamic (I'm guessing BGP and other things like SNMP
feeding the topology box) you could then use it to balance traffic flows
through your network to avoid congestion on certain links - that's a win
for everyone. You could get webbrowsers to look at it when you've got
multiple A records to chose which one is best for things like Flash
video etc.
