Indeed the LAN's we run here have upwards of 1000 gamers. If you want to
put a LAN check in, you would need to compare to see if any of the below
apply:
1. The server is in the same subnet ( defined by that specified on the bound
interfaces ) as the client.
2. The server is in the same "private" address range as the client.
See RFC 1597 for the definition of these:
http://www.safety.net/sum1597.html

CIDR totally blows a class C subnet definition of a "LAN" out of the water
we often run /23 /22 etc.
