Here is an interesting question.  When you have a connection from a client
to the server, how do you get the IP address of the server from the connection.
For example:  I want to have one machine aliased to several IP addresses, 
yet I need to know which IP address was used to connect to the machine.

Any ideas?  I don't want to do a kvm_read, or mess with raw sockets if 
I don't have to. 

Hopefully this is clear.
