Hi Andrew. In order to add/change nics I also run:

# Find out, what nic configuration we have. This is needed for later on to fill the database
# correctly.
if [[ `ifconfig -s -a | awk '$1 != "Iface" && $1 != "lo" && $1 != "pan0" { print $1 }' | wc -l` > 1 ]]; then

#Use these for the defaults if we cannot automatically determine which to use
#TODO: Error out and instruct the user to setup a working connection? Or ask them to manually choose?
extif="eth0"
intif="eth1"
if route -n | grep -q '^0.0.0.0'; then
#We have a default route, use it for finding external interface.
extif=`route -n | awk '$1 == "0.0.0.0" { print $8 }'`
#Use the first available interface as the internal interface.
for if in `ifconfig -s -a | awk '$1 != "Iface" && $1 != "lo" && $1 != "pan0" { print $1 }'`; do

In a script to set values up in the DB appropriately after changing udev net.rules. I am sure that you have a less complicated method of doing this... just thought I would throw it out there.
