Listening on multiple devices in promiscous mode

Hi all,
 
I need to capture from 2 interfaces on a machine in promiscuous mode.
This is because we are routing a copy of 2 load balanced streams onto a
box for monitoring.
 
I'm aware it isn't possible (?) to listen on "any" with a pcap_open_live
in promiscuous as the flag is ignored, but is there a way of listening
on a set of interfaces in promiscuous mode?
 
Many thanks.
 
Pete
