I would like the ability to determine the "live" NIC card.

Please see this post for further information. http://kixtart.org/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=2&t=002661

Currently KiXtart suppots IPADDRESS0,1,2 etc.. but you don't know which interface is the correct one that is being used with the current logon.
