RE: 2 NIC's on same network, possible?

  Your Perl script should work fine *IF* you've given both NICs the same MAC address -- in which case, having both interfaces up at once is a very bad idea.

  (In fact, this is more or less how real fail-over systems like HSRP work. Two gateway routers talk to each other privately, and when one stops talking, the other assumes responsibility for the gateway IP and MAC addresses that clients have been told about via DHCP (or static config) and ARP, respectively.)
