If your switches support the Nicira / Open vSwitch extensions, an easy way to 
do it might be to modify RouteFlow very slightly so that it installs rules in a 
table that isn't the first one.  Then use OVS's learning functionality to add 
rules that have IP/port (which you'd use for monitoring), but always still jump 
to the RouteFlow table to do the actual forwarding.
