Perhaps, but if you ever use VPN, you have more than one network 
interface (one physical and one virtual). This was why I created my 
little script.

Also, many new motherboard have 2 NICs and also a firewire port that 
also functions as a NIC. All in all, more than 1 network interface is 
not that uncommon (I have 4 on my pc but up to 3 on my laptop (NIC, 
wireless, VPN).

Anyway, I gave my script to aid, not to start a discussion.

Have fun ;-)

Bernhard
